QBI Error?

[Tammy1604]

I used TT and am now being audited for QBID calculation errors. So far I owe $3300 for 2020 and $3400 for 2019. This is a huge software error and everyone should use caution with trusting this calculation.

Same thing is happening to me. Different loss carryover numbers, of course.  But I too had a rental net profit, not a loss, for several years.  So, when TT carries over this misinformation of a QBI loss, I would think it would falsely decrease my tax liability, (also therefore increasing my refund).

However, the crazy thing is when I override the line to reflect ZERO loss carryover, my refund goes up!

My tax liability should go up, refund down when I change data to show more let income.

This is very disturbing.

This sounds a lot like my issue. But when I correct it by entering ZERO in the carryover QBI from 2019, I would think my tax liability would go up because I am losing a big deduction. But instead my refund goes up!

This seems so wrong that I switched it back to the original "error" entry.

No, you've got it backwards.  As QBI goes UP, your deduction goes UP, so your tax liability goes DOWN.  The lower your QBI the less your deduction, the more your taxes.
