After you file

My daughter e-filed accidentally not checking the "someone else can claim me as a dependent".  I e-filed and was rejected trying to claim her as a dependent. She e-filed an amendment to change the box to "someone else can claim me as a dependent" the same day and accepted by the IRS.  I tried to e-refile the same day and it was rejected again.  Do I have to wait longer or do I now need to mail in my return?
