On the K-1 I'm working on, boxes 1, 13K, 17A, 19A, & 20N, V, & Z. In addition, boxes 5, 6a, 6b, 10, 13A, 17B, 18C have the numeral zero printed in them.
The issue isn't tied to those boxes, I suspect. Rather, it is tied to the sale of the MLP which ends up being recorded twice, once in the 1099-B info and once in the K-1 info. There are numerous historical posts on this forum dealing with the issue, but they apparently are no longer relevant since TT has since changed. (As one small and possibly irrelevant example, most of the previous posts state to indicate that the sale is a final sale of all of one's interest. That/those options are no longer available in TT.)
The former "best" answer has been removed by the TT hosts of our community apparently because of the changes to TT. I'll try to post a link to the removed answer:
