You need to file tax year 2020 tax return. If eligible, you should be able to claim the 2nd economic impact payment not received as a credit on Form 1040, line 30. Please refer to "How do I claim the credit" section of below link. 

What is the Recovery Rebate Credit and am I Eligible?

The stimulus check is an advance on a credit you can receive on your 2020 tax return.  If something went wrong or you did not get the stimulus check in 2020, you can get it when you file your 2020 return in early 2021

The Recovery Rebate Credit will be found in the FEDERAL REVIEW section. ( you should see "Let's make sure you got the right stimulus amount”)  If you are eligible it will end up on line 30 of your 2020 Form 1040.

Make sure that you enter ALL of the stimulus money received for the 1st and 2nd stimulus for yourself, your spouse and your children.
