I encounter the same situation and got same error message. In my case for my two rental, on each rental on the 2023 Form 4562 Line 13, was blank, no number. On a 2023 Summary Form 4562 Line 13, there was $12,850, which was transferred to 2024, where TT said it was in error (same error as show in this post). Even with the help and 6 hours on the phone with TT Live advisors we were NOT able to resolve error. We did a workaround which allowed me to file my 2024 taxes, but I guess I've lost the $12,850 of 179 carryover. ðŸ˜
