After you file

@BentoBoxLover  It was a while back, but I believe I printed out a Form 3588 Voucher and attached a note stating that I had paid the $800 electronically months prior and if there were any questions to please reach out to me. I got my return back stating, but for a different reason, but no mention about the Form 3588 so I'm assuming it went smoothly?

 

However, I still have not received my Federal return yet. It has been two months and its a bit concerning.
