1) Once you filed the first one...and it was accepted, then that cannot be stopped. SO you get that original refund.
2) Then you amended the tax file ......and an amended tax return may take a few months to get processed after you mail it in to the IRS (and state if applicable). So...when did you mail that paperwork in at the Post Office? And did you send in a check along with it to pay back what you owed as a payback? ( Or did you pay the extra online? They may send those $$ back if they didn't process your amended paperwork yet)
