Can u give it to me in really stupid steps on filing for my fiances' stimulas checks. i keep getting lost and confused.

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 ad 2nd stimulus for yourself, your spouse and your children.

Congress passed the 2nd stimulus bill at the end of 2020. Both stimulus checks were an advance credit for your 2020 tax return,  The 2nd stimulus checks started going out at the very end of December 2020 and continued into early January 2021.  When you fill out the recovery rebate credit it is important for you to enter the entire total of the amount you have received for yourself, your spouse, and your dependent children so far.   Entering the wrong amount might delay your 2020 refund.

It should help you if you bear in mind that the purpose of the question is to determine if you have already received the amounts you should have received
