I did not get None of my 4 Stimulus check 4,000

There have not been four stimulus checks.  There have been three checks.   The first one last year was for $1200; the second one was for $600, and the most recent one was the 3rd one for $1400.

You can file a 2020 tax return and get the first two payments as a recovery rebate credit.  There is no place to enter anything about the 3rd check on your 2020 return.  The 3rd check is issued separately by the IRS.

The stimulus check is an advance on a credit you can receive on your 2020 tax return if you are eligible.   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:
