If Turbo Tax told you that you needed to mail something it was probably the whole 1040 tax return and W2s.
Did you go all the way through the File tab, through the 3 steps and hit the big orange Transmit Returns Now button?
You can check your efile status here
https://turbotax.intuit.com/tax-tools/efile-status-lookup/
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?
