After you file

Sorry, I was not clear enough before.  I (the mother of the dependent) need to amend the return because the child is not marked as a dependent.  My tax return was rejected because the child did not mark herself as a dependent and it looks like I am trying to file a non-dependent on my tax return.  In the app, the amend return does not appear.  Is there a delay in being able to amend the return?  The federal says it has been accepted.
