After you file

The  different addresses should not be an issue.  Since your mom cannot e-file she just has to print, sign and mail her own return.  She does not have to wait for your return to be amended--since that will take about 4 months.  The IRS will process her return that claims you as a dependent.    You do not have to live with her to be a "qualifying child.'  (Are you a student?)
