Hi,
I had similar issues yesterday. I was pulling my hairs and searched on an answer online, wasting so much time and finally figured out something to work around this issue.
I have K1 income/loss and get carryover losses from prior year. At the review stage, the smart check kept on giving me error message saying Qualified Business Operating Loss needs to be entered. When I entered some number, it was populated to 2019 or other prior years.
A simple solution I did to fix this bug is going back to my K1 section. Find the section which shows/let you input the carryover loss from prior years. It is separated into three sections: 1st for regular tax, 2nd for AMT, and 3rd for QBI.
In the QBI section, there is one page split into two sections. Top section shows for regular tax and follows 2019-2023 boxes to enter the carryover amount of each past year. The bottom section is similar but for the QBI carryover amount of past years. If you see numbers shouldn't be there, or show an empty box for one historical year, just enter "0" to overwrite the value. Do not leave the entry box empty. To the system an empty box here doesn't mean "0", but a value needs to be entered. Do it to every K1 schedule you reported. My error messages went away after I input all the 0s in this section.
From my understanding, there was a bug discovered in this QBI section back in the 2021 forum discussion. I guess this bug was fixed later but not done perfectly. So a "0" is required to be entered in this section, otherwise same bug pops out.
Hope this silly yet simple solution will help to solve your problem.
