According to the IRS requirements, I was eligible to receive the child tax credit monthly payments but never did, is there something I can do to find out why?

TurboTax has no involvement in the monthly child tax credit payments.  The IRS is sending out those payments by direct deposit or by mailed checks or cards.

If you have a return or amended return still pending in the system it affects your eligibility to receive the monthly payments.

  This is a brand new system thrown together by the IRS after Congress changed tax laws in the middle of the tax season.  There are going to be bugs, glitches and mistakes made and folks will unfortunately have to be patient (or endure aggravation and inconsistency) until they sort it out.

If you do not receive the monthly payments you will be able to get the CTC on your 2021 tax return.

Q.  Is there something I can do to find out why I didn't receive the monthly child tax credit payments?

A.  No. You'll just have to wait and claim the full amount when you file your 2021 tax return.
