TaxAct review: 2021 tax software program

Have used Taxact for the past 10+ years. This year again I filed with Taxact. On completion, TA setup a voucher that I owed $4165 which I sent in to the IRS with payment. The other day I received a letter from IRS stating I underpaid some $486.27. Upon reviewing the return I saved, it appears that Taxact program did not take into consideration that I was over the $75, 000 limit and should have had my recovery rebate credit remove. That would have upped my payment voucher to the correct amount.

Have tried to find a person to talk to at Taxact but without any luck. Want everyone to be aware of the issue they have in their program.
