Pending means it is still waiting to be sent to the IRS. You need to sign in to TurboTax, make the changes that are keeping the return in pending and then e-file it. You did not file if the return is pending.
Who says pending? Turbo Tax or the IRS? Check and see if your efile was Accepted. It should only take 2 days or less to be Accepted or Rejected.
If you used the Online version 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?
