I am told that "Box 20 Code Z (on Sch K-1) has been selected but no Section 199A income has been entered on Statement A", but I entered199A info. Anyone else seen this?

This was shown as a "Check This Entry" message during the "Federal Review" process, but even if I knew what it's trying to get me to do, I'm not provided with an option to input anything from this view. I appreciate any suggestions, whether it's about the TurboTax interface or others' experiences with Schedule K-1!
