I found that one of my pass through entities is not designated as an SSTB. This is the one entity that has a loss for 2024. I had all pass throughs marked as SSTB. Once I changed this one, the 8995-A schedule C populated with the carryover from 2023 and the current year loss, added together correctly, with the new carryover total. (However if the entity was marked as SSTB/actually was an SSTB, the 8995A schedule C would not fill in.) I do not know if you would have to paper file in this situation.
If I understand it correctly: This carryover amount could be applied at some time in the future, if qualified business income ever occurs, netting against it and reducing the QBI that the deduction is calculated on, resulting in a lower deduction. So that is why letting it drop off or not carrying it forward would not be advised.
