Stimulus payments from 2020 are no longer available.
If you were not claimed as a dependent on a 2021 tax return, you should have received the 2021 stimulus of $1,400.
Go to this IRS website for a tax account and check to see if the IRS sent you the stimulus payment - https://www.irs.gov/payments/online-account-for-individuals
If not, then you either have to file a 2021 amended return or if you never filed a 2021 return then you have to file a 2021 return or an amended return on or before April 15, 2025.
You complete the Recovery Rebate section of the 2021 return.
