The IRS checks all claims for the Recovery Rebate Credit. They will find the error and correct it. You don't have to do anything except wait. But it will take a while. They process the Recovery Rebate Credit corrections manually, and they are severely backlogged.
Do not file an amended return until you hear from the IRS. Filing an amended return will just cause confusion, problems, and further delay. If the IRS makes the correction as expected, you will not have to amend.
