@JulieS, thank you for continuing to address this, but it is no longer me who needs a reply.
The original bug I and others posted about two years ago was that all the source forms either had nothing relevant in them or didn't even exist, yet the "QBI worksheet" was being populated *automatically* by TurboTax with all zeroes, which then caused the 8995-A to be generated, also with all zeroes.
I have no idea whether this is still a problem now, since I haven't started taxes yet this year, but at that time, *all* the possible things that might have applied, which several responders helpfully provided, simply did not apply, at all, period.
@ghandrewsIf the solution I posted at that time doesn't work for you, then there may be a different problem now. Alternatively, maybe you didn't delete the relevant worksheet further down the chain; merely deleting the 8995 form itself absolutely did not fix the error. But you should also check the possibility that you do have something obscure applicable somewhere, per JulieS's suggestions.
