Well....it is too late for the 2020 stimulus amounts. The deadline for those payments was May 17, 2024. If you were eligible for the 2021 EIP payment the only way to get it now is to file a 2021 tax return, which has to be mailed to the IRS. E-filing is closed for 2021 returns. If the 2021 return is not sent by April 15, 2025, it will be too late for that one too.
Look at your online account with the IRS to see if they sent you $1400 in 2021.

If you could be claimed as someone else's dependent in 2021, you are not eligible for the payment.
If you were eligible and do not receive a payment soon from the IRS, the other way to get the payment is to r amend your 2021 return to use the recovery rebate credit before April 15, 2025. If you did not file a 2021 return at all, then prepare one and mail it in.
