On IRS Schedule K-1 (1065) or IRS Schedule K-1 (1120S). After answering the questions and inputing Box 20 Code Z it ignores my entries and tells me I cannot efile.

I get this "Sch K-1 Wks-Partnerships (name of company removed): Box 20 Code Z has been selected but no Section 199A income has been entered on Statement A.” TT does not allow me to make any further changes and I did enter Section 199A.
