Will we still receive $1100 in stimulus for my baby born in 2020 if we forgot to fill out a recovery rebate form??

Yes. If you e-filed and did not fill in the recovery rebate form and did not get credit for your child born in 2020, you will have to amend your return once the IRS accepts it. 

You cannot make changes while your e-file is pending. Once accepted, please follow the instructions on the page How do I amend my 2020 TurboTax Online return?

After you start to amend, you can follow these steps to enter your stimulus payments received:

1. With your return open, search for stimulus with the magnifying glass tool on the top of the page.
2. Select the Jump to Stimulus in the search results to directly go to correct TurboTax page.
