1065 K1 - Box 11 code ZZ, LT Cap gain - not populating in Form 8949 or Schedule D

My spouse has a 1065 K1 with an value in Box 11 (Other income) with code ZZ. In the description it says "Nonportfolio long term capital gain". In TT, after inputting the requested data, it looks like this value is not populating through the rest of my taxes (form 8949 or Sched D). When I go to the TT K1 Partner sheet, under section B, Box 6a, the field for Non-portfolio capital gain is empty and locked, so I cannot update that field. Am I correct that I should have to report this long term cap gain? If so, how can I get this amount to populate through TT?

Thanks!
