It appears that TurboTax has been calculating previously disallowed losses from qualified business incorrectly the past few years. I think this might have happened because of bugs in prior versions of turbo tax which I'm told have been resolved now, but clearly didn't correct the amount of previously disallowed losses on my returns because Turbo Tax always populates new returns based on data from previous returns (which would have been incorrect). What's the best approach to fixing this issue so going forward the amount of previously allowed losses is correctly reflected in the QBI Component Worksheet?
