Truly confusing language from TurboTax. The k-1 has sub-categories for many of the Part III items, A being the first subcategory, and meaning different things for different questions. Question 20, for instance, has space for a series of responses, the first of which is labelled "A," with the amount to the right of it. For a list of five or more entries, probably including your "Z", there is a statement with codes, perhaps including "20Z1 Section 199A Publicly Traded Partnership (PTP) Income" or something like that, with an amount in the right hand column. I think that would be the number you need. I suspect that TurboTax is just lazy about rewriting its very awkward language.
