Same problem here. I submitted tax returns on 3/3 and it was rejected on 3/4 (inherited IRA that I don't have, but I did make a 2020 non-deductible traditional IRA contribution with subsequent backdoor Roth IRA conversion (using downloaded TT home and business software)). A phone call with a TT representative resulted in the same conclusion.. an update should be coming on 3/5 (no ETA) to fix this problem, then re-file my tax return after installing this 3/5 update...
