Deductions & credits

if your child was born in 2020, be sure that you answer that your child lived with you the ENTIRE year 

there is a question about whether the child provided more than 50% of his financial support; you are to answer "no" (the question is oddly worded).

you entered the child's social security number?

re-check the date of birth.....

 

near the end of the federal review section it will ask you to enter how much you ACTUALLY received for each stimulus payment,

 

Then look at Line 30 of Form 1040.  is the amount there what you are expecting? if you got paid the correct stimulus, other than one child, there should be $1100 on this line.
