After you file

That is correct.   Since you had to check the box ''someone else can claim me'', you would not be eligible for the 3rd stimulus ($1400).    If your mom didn't claim you, she would not have received the $1400 either.    Since you could have been claimed, your mom (or whoever could claim you) could file an amendment, claim you, and receive the recovery rebate.
