Do I need to mail in my taxe forms

[Critter-3]

If you efile a return successfully then there is nothing you need to mail in .

Does it say something about mail?

Did you efile?  You can check your efile status here

When you efile you get back 2 emails.  The first email only confirms the transmission.  The second email says if the IRS (or state) Accepted or Rejected your efile.

When you log into your account you should also see the status and if it was Accepted or Rejected, Started, Printed, Ready to Mail, etc.  What does it say?
