When filling it out it says to enter the amount of your advance payments using one of the following, either the 6419 or the IRS Child Tax Credit Update Portal. When I look at the portal, it lists all of the advanced payments that were issued, which add up to the actual amount I received. I haven't had her check to see if it also shows payments for her yet, but if it doesn't then I'll enter the full amount on mine.
Unfortunately, I have to pay them back as I make to much now that I'm filing as head of household and not jointly.
