First, in the K-1 interview you have to check the box that you had an entry (entries) in Box 13.
When you come to the "Enter Box 13 info" screen, select "T- Domestic production activities" from the drop-down menu for "Code". Don't enter an "Amount" on this screen.
Select "Continue" and you will have two screens to enter the T1 to T7 amounts. You will have to interpret/match the descriptions on your Supplemental Information sheet to those on the TurboTax screens and enter the amounts.
