After you file

IRS sent a green form 3531 asking for “a valid original signature”, “supporting documents for federal income tax withheld amount”, “form 1 to support line 8”, and “form 3 to support line 20”.

 

This was sent to me in response to the check and payment voucher I mailed to the address on the voucher which is in NC, but it looks like they forwarded the FedEx shipment to Austin.

 

I’m guessing they got the payment/voucher from me and maybe their system wasn’t updated with my actual filing yet so they thought what I sent them was my official tax filing? Although they had no problem depositing my check.

 

On the IRS site when I logged in, said the filing was received and showed the amount I owed less my payment they already received.
