After you file

first, the 2nd stimulus payment is not programmed in yet.  it should be there by the time the filing window opens in late January as it affects everyone

 

did you fill in the stimulus questions at the END of the interview? 

 

so you should see $500 on Line 30 on Form 1040.  

 

depending on your income it is possible you are not due any more stimulus, even for the child, but we have to understand more first.   Did you receive the entire $1200 or $2400 from the first payment? if no, how much did you receive?
