Turbo Tax has me in a endless loop because it is asking to fill in a line on form 1065 that is not on my K1. How can I get out of the loop?

Which boxes are filled in on your K-1 and which box is TurboTax requiring an entry for?

Boxes:  5, 6a, 6b, 9a, 13, 20, 21.

When it performs the check, it pulls up the 1065, various lines asking for deduction entries and interest.  I have been posting K1's for 15 years on TurboTax and it has never asked this question, plus it will not accept zero.  I gave up and printed the forms so I can mail the return because it will not let me E-file.  It also will not let me back in unless I start an amendment.  Is there another way to open the 2024 return without an amendment?

Yes, you can access your TurboTax return after filing using these steps:

Note that you are NOT actually changing your return - you are simply opening your return again so you have access to your entries.

•  Log into TurboTax using the same username and password as you did before.
•  Click on Tax Home from the menu on the left.
•  Under Your tax returns & documents, select the current tax year, then click on Add a State.
•  You now have access to your entire return. You may navigate using the tabs or Search box as you did while entering your information. Do NOT change anything, in case you do actually need to amend your return.

It would be helpful to have the exact wording of the SmartCheck message you received. A screenshot would also work. If you have already mailed your return, resolving this issue may not change what you sent to the IRS. In most cases, the missing information doesn't affect your taxable income.

Thank you. I am not able to look at this again until next week. I will send screenshots. 

During the check process, this is what shows:

I checked the printed copy and all the numbers from the K1 are on the form.  It's like it wants me to add more numbers that do not exist.

Try this:

1. Working through the Schedule K-1 entry screens, check the box for Box 20.
2. Continue to the page to Enter Box 20 Info.
3. Choose the appropriate Code from the dropdown menu (such as AJ - Excess business loss limitation)
4. Do not enter an amount here.
5. Continue to the page to Enter Box 20 Other Information Amounts.
6. In the section under "Other Description", enter the Supplemental Information provided with your K-1. Choose relevant descriptions then enter the amount for each line.
7. Continue to back to the K-1 Summary page.
8. Run SmartCheck again.
