I should be eligible for the $1400 payment that the IRS is sending out to people whom did not claim the Recovery Rebate on 2021 tax return. How do I claim/request it?

It says the payments were sent automatically, but I never received it. But I also have no idea what address or bank account I would have been using back then. Can I file a tax return for this year and claim this credit or do I need to file 2021's tax return? Thanks, Confused, broke, and hopeful.
