How do I enter each K-1 Line 20 amounts, eg 20AD, 20AE, 20AH1, 20AH2 and 20AH3?

To enter the line 20 amounts from your K-1, please follow these steps:

1. Click on Federal > Wages & Income
2. In the S-Corps, Partnerships, and Trusts section click on the box next to Schedule K-1.
3. Click Yes on the next screen, Did you receive any Schedules K-1?
4. On the Tell Us About Your Schedules K-1 screen.  Click on the Start/Update box next to Partnerships/LLC (Form 1065)
5. If you have already entered K-1 information, you will see a Summary screen.  Click Add Another K-1 to enter your information  (or click on Edit to continue with the existing form entry).   
6. If you haven't started entering K-1 information, continue through the screens, entering the requested information.
7. On the screen, Check Boxes that Have an Amount, make sure Box 20 is checked and click Continue.
8. On the next screen, Enter Box 20 Info, enter the information.  Put each code and amount on a separate line.  For example, on the first line enter Code AD and the amount, Code AE on the next line with its amount.  You will have 3 lines with Code AH.
   
9. When you get to the last line in the table, a new blank line will appear.

Code AH is for "Other information."  There should be a statement either at the bottom of the K-1 or separately, that explains what the Codes AH1, AH2 and AH3 pertain to.  These figures can be entered on the next screen, Enter Box 20 Code AH Amounts.
