Deductions & credits

@justine1195     I agree ... you are not making any sense.   If you have 3 kids and no one else is claiming you or the children on their tax return then you should have filed a return to get the child tax credit if nothing else because you did not need income in 2021 to get this refundable credit.  AND  if your refund only consisted of refundable credits then you were not eligible to use the refund processing service to withhold the TT fees  AND   there should have been no fees to pay because you could have used the  free TT online  program   OR   one of the IRS FREE FILE options here :   https://www.irs.gov/filing/free-file-do-your-federal-taxes-for-free
