Had a baby in 2021. I also have 2 older children. We claimed the CTC payments for them and not the baby.How do I claim this? Or is it automatic added when doing taxes?

Yes. That will all be reconciled on your 2021 return.

A child born in 2021 is considered by the IRS as having lived with you the whole year.

In the Personal Info section of TurboTax, make sure to add your newborn child as a dependent and indicate that he/she lived with you the whole year.

TurboTax will take into account the child as your dependent and the Child tax credit will be automatically calculated by TurboTax.
