My K-1 has both SSTB and non-SSTB activity on Line 20. So there are 2 values to input for things like Income, Wages, UBIA for my 199A. But there is only 1 box for each on TT. What should I do?

You need to enter two separate K-1 schedules. You will duplicate the federal ID number, name and address, but don't duplicate any of the dollar entries.

Thank you for you this! So even though I only received one K-1, I add a second one here. And the only part of the second one I include is the non-SSTB information that I don't include in the first one, is that right? Otherwise, leave everything blank or enter zero?

Yes, that is correct.  Many times a single K-1 needs to be entered twice to arrive at the correct results in the tax return.  This allows for more clarity for the return results.

On the second one enter only the SSTB information not entered on the first K-1.

Hi. A little confused about this response.  I understand that I need to enter two K-1s, one for SSTB and another for non-SSTB as identified on the K-1 Schedules, but as a matter of process in using TurboTax, do you still enter income/loss values for Box 1 or do you just leave Box 1 blank and ONLY complete the income/loss values in Box 20?
