The stimulus payments that you received were calculated based on your 2019 or 2018 tax return. But those payments were an advance on the credit on your 2020 tax return. The Recovery Rebate Credit is calculated based on your 2020 tax return. Are you eligible based on your 2020 AGI? If so, you get the credit for the additional amount that you did not receive in the earlier payments.
Did you correctly enter the amount that you received for each payment?
