If you have E-filed, there is nothing more you need to do. You do not need to mail anything in. E-filing is your electronic signature.
- If you e-filed, start by checking your e-file status. (wait 24 hrs to check)
- Once you've received confirmation your federal return has been accepted, you'll be able to start tracking your refund at the IRS Where's My Refund? site. https://ttlc.intuit.com/replies/3300211
