Millions of taxpayers have not yet received there federal tax refunds.
So you are not alone. There is nothing you can do other than being patient and check the IRS website weekly for the status of the federal tax refund.
If you did not receive the 1st or 2nd stimulus you use the recovery rebate credit to get it added to the refund on your 2020 tax 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.
The third stimulus payment will be released automatically when the 2020 return is processed.
