If you had an amount on line 30 for the recovery rebate credit, the IRS cross checks every return that has an amount on that line. They can see if they already gave you the stimulus payments and if they did, then the refund shown on your return is reduced or you might end up actually owing tax. So if an error was made with your RCC, you were going to owe tax anyway. You will need to pay the tax due. If the IRS assessed penalties or interest for paying the tax late, you can discuss that with TT.
