My Section 199A income is divided between Trade/Business and Pass-Through Entities. What total do I use? Also, in the footnotes, it allocated between SSTB and non SSTB.

In the final check, I get a message "Sch K-1 Box 17 Code V has been selected but no Section 199A income has been entered on Statement A."

I entered the QBI from statement A in the supporting details box, but still get the message. What should I do to fix this?

Delete the K1 form and then reenter it again. Record the information in Box 17 with code V and the dollar amount that is listed on Statement A.  See if that works. 

I had the same issue..your delete K1 and reenter isn't what is really required, but doing so helped me understand the actual problem.

(My 1120 for 2019 isn't even started yet, so my objective was creating an *estimate* K1 and figured I'd update it later after my accountant finishes my biz return), so:

* I initially entered my K1, checked that I had boxes 16 and 17 (key to QBI calculations).  
* I did NOT enter any of the codes for box 17..just clicked continue (I first just wanted to get a rough idea on how my K1 income was going to affect my overall tax liability).

* I then just clicked through the rest of the K1 to the end.  As expected it didn't ask me any of the QBI questions (since I didn't enter any values in box 17)
* My plan was to then review my prior year K1, and figure out from it how to estimate my box V,W and X

* A few minutes later I select Edit for the K1, fill estimated values for V,W and X

* Confusingly, then I get a QBI dialog that gives you a check box for all K1 items (e.g. income, sect179, W2 wages, etc...)

* Initially, I checked ordinary business income and just reentered the same value I had already entered for Box 1 of the K1

* I didn't really understand what the other checkboxes were for as they seemed to be redundant

* I continue through the rest of the K1 questions and STILL no QBI credit

* I search here and find the delete and re-enter suggestion

* I make sure I enter values for V,W,X which then triggers the QBI dialog

* This time I realize Turbotax is insisting that you check and re-enter values for 'ordinary business income' *AND* 'w2 wages'....the later was what I was missing the first go around  (which is obviously key as if you don't pay any wages you don't qualify for QBI)

* This time, after step through the rest of the dialogs I can see my refund go up substantially as the QBI kicked in

At no point does Turbotax warn you that your answers to the dialogs are conflicting (e.g. you entered wages on K1 box W) yet when the QBI dialog pops up you fail to even check the 'I paid W2 pages dialog and enter the same amount there).   Absolutely no error is reported when you run 'final check' either.

This is the most ridiculous Turbotax bug ever.  Had I not been paying attention this would resulted in an approx ~$200K tax overpayment.  I cringe to think if the IRS would have noticed either.  Seriously!?

So, the 2019 K-1 has different codes - just a code Z with two numbers - the rental loss and the unadjusted basis of assets.  No longer code AB.  There are options in TT for Code Z including Ordinary Business Income / Loss and UBIA of qualified property.   I'm still researching UBIA, but does the Unadjusted basis go here?  I received no K-1 instructions.

This year you should have also received a statement with the K-1 which also needs to be entered. 

Dear DanielV01,

Our Unadjusted Basis is labeled X in box 17 of the K-1.

When filling out the 199A on Turbo Tax I do not understand which box to check to put the amount in.

Thank you in advance for your assistance.

You'll need to put the Unadjusted Basis information on the K-1 Section 199A Statement into the "....has UBIA of qualifed property" box on the "We need some information about your 199A income or loss" screen.

Enter the code V when you enter the K-1 box 17 screen, but you don't need to enter an amount.  Continue on, and you'll find the screen you need.  When you check the box next to the UBIA of qualified property category, a place will open up to enter your amount.  This screen must be completed with the amounts on your 199A statement in order for your K-1 QBI information to be correctly input into TurboTax. 

To get back to the K-1 summary screen and find the Schedule K-1 to edit, click the "magnifying glass Search" icon on the top row, enter "k-1" in the search window and press return or enter, and then click on the "Jump to k-1" link to find the K-1 you need to edit.

Here is a screenshot of the "We need some information about your 199A income or loss" screen, you enter the Unadjusted Basis information by checking the box next to the last line on that screen:
