Error with max filings reached

Did you properly convert the file by mail return to e-file? If not, please follow these steps.

Sorry, I should have specified I’m using the TurboTax Deluxe desktop version. Can you please give me the instructions to convert from mail to e file? I have not yet mailed the return. Thank you!

In TurboTax CD/Download versions, these steps will change how you'll file your tax return(s).

1. In TurboTax, select the File tab, then click Continue.
2. On the E-file Your Federal Return for FREE screen:
   • There are two choices: E-file and File by mail.
   • Change your old selection to your new choice; check the E-file button.
3. On the Select the Returns You're Ready to File by Mail screen,
   Check the buttons for the federal and any state returns you wish to e-file.
4. Continue through the filing experience.
   You'll need either your last year's AGI (adjusted gross income number from last year's return) or an IRS PIN number, the interviews will assist you.
5. To e-file your tax returns, be sure to continue until you've clicked the orange Transmit Returns Now button.

It will not me allow to change it from mail to e file because it already counted it as one of my five filings.

We cannot change the nature of the software.  It thinks you have done 5 efiles and that is it.
