Ok ... cool your jets. Here are the facts :
1) no matter what the ex does on their return all your daughter can do is mail in her 2019 return and wait forever for it to process ... the virus has the IRS 3 - 6 months behind in processing mailed in returns.
2) the ex could not get any extra stimulus for a dependent over the age of 16 so they got nothing for this error and has to pay back the $500 she did get when the IRS catches up with them
3) if the IRS doesn't release the stimulus check to your daughter after processing the 2019 return then she can get it on the 2020 return she files next year... so she doesn't lose it but merely needs to wait a bit
