Shorted $500 on last year's refund due to a child tax credit payment I didn't get. Spoke to irs and it was corrected, but I never got payment. How to get it this year?

There is no way to reconcile a short 2021 refund on your 2022 return.  Each tax year is separate.  You have to deal with the IRS to pursue the amount you believe it still owed to you.

To call the IRS:IRS:  800-829-1040  hours 7 AM - 7 PM local time Mon-Fri

Listen to each menu before making the selection.

First choose your language. Press 1 for English.

Then do NOT choose the first choice re: "Refund", or it will send you to an automated phone line.

Instead, press 2 for "personal income tax".

Then press 1 for "form, tax history, or payment".  

Then press 3 "for all other questions."

Then press 2 "for all other questions."  It should then transfer you to an agent.

file a 1040-X claiming the $500 you did not get.

If IRS disapproves saying they sent it to you, you'd have to initiate a trace on a lost payment.
