Thank you very much for replying to my question. Looks like I have to file an amended return. Too bad.
I did everything correctly as always (I have been using TT for many years) and I firmly believe it's the buggy TurboTax that made the error - failed to calculate recovery rebate credit for me. I am disappointed by TT. I am not sure if I will continue to use TT next year.
Once again, thanks.
