Can I submit amended form in order to add ssn for my dependent child (I submitted my return with ITIN, and didn't receive child tax credit)?

I need to apply for SSN for my child and it will take ~3 weeks to get it - so I'll have this information around mid week of May 2019.

Of course you can. You have about three years to file an amended return.

Here is how to amend your tax return(s) once you get your child's SSN: How to amend (change or correct) a return you already filed.
