After you file

After filing using Turbotax Deluxe (Windows), I get an Electronic Filing Instructions page which includes a section "What you need to mail (in my case form 8453 to Austin, Texas) -  Mail form 8453 promptly after your return is accepted with attached forms ....".  These is the form that I wish to send.


Right, so mail it to that address. That is the only way to file a 8453.
