Get your taxes done using TurboTax

Box 4c of the K-1 is simply the total guaranteed payments, the sum of boxes 4a and 4b.  You do not have to enter this figure in the interview.  TurboTax will do the math and the total will appear on box 4c of the actual K-1 form.

You can see this by going into Forms Mode:

1. Go into Forms Mode by clicking on the Forms icon in the top right of the blue bar. 
2. In the Forms in My Return list on the left, click on K-1 partner (partnership name).
3. The form will open on the screen to the right.
4. You will see that box 4c is populated with the total guaranteed payments.  [See screenshot below.]
5. To return to the interview, click on the Step-By-Step icon in the top right of the blue bar.
