Late adding

[Londonlewis021]

I had my son Nov of last year. I never received his ssc in time to get the 300 people were getting for their kids.  I also was never able to claim him on my taxes. Is it to late to add him. If not what can I do

Please explain----why did you not claim your child who was born in 2021 on your 2021 tax return?   Did you file your 2021 return before you had his Social Security number?  What was on line 28 of your 2021 Form 1040?

I’m just now receiving his ssc so I was never able to add him due to not knowing his social. Yes I’ve already filed.
