After you file

Please be aware that I cannot see the details of your return and I had encountered multiple situations where that box under the SSN was the issue for not getting the stimulus payment for the child. Your child will still show as a dependent on the return and under the "My Info" section but won't qualify for the Recovery Rebate Credit and Child Tax Credit if that box is checked.

You stated that you got the Child and Dependent Care Credit but for that credit it does not matter if the child's SSN is valid for employment. 

If you verified that none of this applies and you AGI in 2020 is below the limit then you might have to contact TurboTax for more detailed help: What is the TurboTax phone number?
