Did you go to the Federal Review section and complete the questions for the recovery rebate credit?

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.

Click on Tax Tools on the left side of the screen. Click on Tools. Click on View Tax Summary. Click on Preview my 1040 on the left side of the screen.

Even if  you are not “prompted” to enter the stimulus information, you can access to the section directly by following these steps:

• Sign in to your account, select Pick up where you left off
• At the right upper corner, in the search box, type in "stimulus" and Enter
• Select Jump to stimulus
• Follow prompts

Yes I went through the steps to claim the Recovery rebate and at the end of the step it agreed that I was entitled to it but at the end when it summed up what i was getting, the rebate was not included.
