@Thenasdois28 - it'll work itself out. There are press reports that in many cases the IRS didn't pick up all the eligible dependents.
worst case, when you complete your 2020 tax returns next year, there will be a 'settle up' section of the return where you'll get the credit for the $500. I know many need the money now, but there is a process to fix this kinda stuff, it just isn't immediate.
