There is no indication on the Form 8453 that a copy of the payment voucher should or should not be mailed. Is it just a coincidence that they seemed to print together?
On Form 8453, Form 8949 box is checked. The form says to submit Form 8949 if I elect not to report transactioins electronically on Form 8949.
But I confirmed that Form 8949 was electronically submitted.
What should I mail, if anything?
