Per IRS: Eligible taxpayers who did not file 2021 return must file a tax return to claim a Recovery Rebate Credit.

You need to file and claim the Recovery Rebate Credit by the April 15, 2025, deadline.

Your post is not clear.   The stimulus checks were issued for 2020 and 2021.  There have been no other federal stimulus checks since 2021, so not sure what checks you are talking about.   Are you saying you filed tax returns for 2022 or 2023 and did not get your refunds?   What is the issue?   What "money back" are you asking about?
