I had A child born in 2022. Do I enter those as a dependent for 2022? The form says it is an invalid birthdate?

Yes, that is correct that it would an invalid birthdate since you are completing your 2021 income tax return. 🙂 Your child was born this year - congratulations!

So next tax season you will add your child. 🙂
