When did you file? Maybe the IRS hasn't processed it yet. It is taking a long time this year, like over 6 months or more. It may not show up in your IRS account until then. Did you efile? Was it accepted?
Did you get the 3rd Stimulus payment back in March-May 2021? It was 1400 per person. The IRS would have sent letter #6475 saying how much they sent you. If you are married you each get a letter for half. Also double check your bank accounts to see if you got a deposit.
Did you have an amount on 1040 line 30 for the Recovery Rebate Credit (to claim a missing 3rd Stimulus)? Line 30 is only if you didn't get the 3rd Stimulus payment. But a lot of people answered the questions wrong and tried to claim it again on line 30 so the IRS has to adjust a lot of returns and reduce the refund or send a bill.
