@samgrif The IRS instructions give exactly one reason why a gross distribution amount should not be on 4a, and that is when the distribution is fully taxable. It then lists a large number of reasons (rollovers, Roth conversions, partially taxable distributions, HSA distributions, QCD contributions, and multiple distributions(!)) as to why the gross amount should be on 4a. So what are all these several types of "certain distributions" that shouldn't be on 4a?
I have personally had returns that were accepted, and then got a letter six months or more later questioning something, so it can happen
