After you file

Hi.  Thank you for your reply, This is a new situation for us as she's never filed before. This box should have been checked on her return because she stated it should be when she went to prepare her taxes, but they made the error (not Intuit Turbo Tax, she used a different service). I claimed her on my taxes a couple of weeks ago and it went through fine as usual.  She e-filed just today in the afternoon but I don't know yet if it was accepted. Will her tax returns be rejected by federal and state because I already filed and claimed her? Will she have to file an amendment? Would it affect my filing in any way? Appreciate your knowledge in this as well!
