After you file

My daughter ended up doing the same thing.  She put that she could be claimed but she really could not and we did not claim her.  She did a amended return and mailed it April 15th from Florida and it is still not showing as received but my understanding is that once they do start opening the mail then it will take another 5 months for it to be corrected and she might get a stimulus and she might not.  This is going to be very unfair for you guys that accidentally made that mistake because if you ever get one it might be mid 2021 or you might just get put to the side and never get one.
