After you file

Be sure you said the new baby lived with you the WHOLE YEAR!  Go back and check that.

 

If you had a child born in 2021- Add them under My Info. You need to answer 2 questions…..

Did your child live with you for the whole year? Answer YES even if they were born late in the year (even on Dec 31).

 

Then was at least half of child's expenses paid by CHILD? Usually is NO.

 

Check 1040 lines 19 and 28 and schedule 8812 for the Child Tax Credit.   It may have been added before you noticed or got to that section.
