I didn't receive the second stimulus for my grandson and myself. The IRS said I need to re-file 2020 taxes to be able to get it. What do I do

If you did not use the recovery rebate credit on your 2020 tax return to get the 1st or 2nd stimulus check then you can amend your return to get it.   There is no place on a 2020 return to enter anything about the 3rd stimulus check, which is being issued separately by the IRS.  Do not amend until your first return has been fully processed.  And....it will take a long time for the IRS to process an amended return---four to six months---so do not expect quick results from amending.

Select your tax year for amending instructions:

• 2020
• 2019
• 2018
• 2017

     What does it mean to "amend" a return?

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.

TurboTax cannot track your 3rd stimulus or tell you when it will arrive.  The IRS is issuing 3rd stimulus checks on its own timetable.

You can use the IRS Get My Payment site to see what is expected for your 3rd stimulus check:
