Since you've already successfully e-filed your federal return using TurboTax, you won't be allowed to e-file it again. I'd recommend printing and mailing your return to the IRS as soon as possible. Include a cover letter explaining what you found when you went to the IRS website. MOST IMPORTANTLY, include a copy of the TurboTax email that stated your federal return had been accepted by the IRS. I would suggest mailing your return using a method that requires a signature receipt. That way, you can prove that the IRS actually HAS your return.
It's not common, but the IRS has been know to "lose" a return. This may be what happened in your case.
Here are instructions to get back into your return to print and file by mail.
