I have entered my Sch K-1, w/ line17 as V, I have a value on that line for the W-2,yet it says No Sct 199A information entered on Stmt A. Where do I find stmt A?

TT brings me to a section, but does not allow any entries. And Line 17 has a value by it. Why won't TT let me continue or tell me where to add the missing information?
