no!
@CatinaT1 - re-read the question!!!! he did not ask specifically about the 3rd stimulus payment.
to get the recovery credit related to the first two stimulus payments, you MUST file 2020,. The first two stimulus were 'advance payments for 2020'. That also means if you do not file by May 17, 2024, you forfeit the credit.
you can only get the recovery credit for the 3rd stimulus payment on your 2021 tax return
