How I did it: As I was entering the K-1 information I noted that there was information for Box 20 (when asked to "check boxes that have an amount or are checked on the form". Then I was asked to "Enter Box 20 info" and entered the code Z as that was on my K-1. I then pressed continue and noted that all my investment income is at risk (in my case); next screen said "We see you have Section 199A income" and the screen after that said "We need some information about your 199A income" and that's where it asked for the ordinary income, W-2 wages. etc. Hope this helps.
