Dependant Michael never received his stimulus

Dependents are not eligible to receive stimulus checks.   As a parent, you could receive the 1st or 2nd stimulus check for a child who was younger than 17 at the end of 2020.   And for the 3rd stimulus, the age limit was lifted, so you can receive that one one for your dependent.

If what you mean is that you did not receive a stimulus check for a dependent that you claimed as a dependent---if that dependent was younger than 17 at the end of 2020 you can get it on your 2020 return if you use the recovery rebate credit on your own 2020 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.
