After you file

She could not "amend" as soon as her return was accepted.  She has to wait until her return is fully processed in order to amend.  She has to prepare a 1040X that needs to be printed, signed and mailed.  It takes the IRS 3-4 months to process a 1040X.  Meanwhile, you have to print sign and mail your own return.  You cannot e-file this year.
