"Sch K-1 Wks-Partnerships: Box 20 Code Z has been selected but no Section 199A income has been entered on Statement A."
This is one of those enormously irritating things in Turbotax (download) that Intuit can't be bothered to fix. It will trip you up year after year. It could be fixed by a programmer in 1 hour but I'm sure it wastes the time of thousands of users every tax season as they tear their hair out in frustration. If you have a real estate limited partnership, the key is that rental income (Box 2) is business income. (Who knew?)
When you get to the screen "We need some information about your 199A income" wouldn't you know but checking the the top unassuming line "[Partnership name] has business income (loss)" causes 4 hidden lines to magically appear. If your partnership owns real estate, entering Rental income (loss) [presumably from Box 2] will clear up the problem and you'll be in a position to get your 199A (QBI) deduction -- assuming you enter UBIA. Of course, UBIA is also entered on a trick line where the you must check the line to make the box where UBIA is entered appear.
Those Intuit programmers they must be rolling on the floor in peals of laughter when each unwitting user suffers through the agony. The frustration could easily be avoided by making the boxes always visible or including a note of explanation on the screen.
