Kris,
I have an ITIN for my daughter born 10/20/21. I believe I can use the ITIN on my 2021 tax return and will receive a $500 credit for other dependents. Based on my readings it appears that since I was issued an ITIN prior to the original due date of the 2021 tax return I would then be allowed to amend the 2021 tax return and claim the CTC and get the remaining $3,100. Can you confirm if this is correct? I haven't been able to find any definitive support in code or publications saying this situation is allowed to amend for the CTC.
Thank you for your time.
Kevin
