E-filing for an original return had to be e-filed by October 15th.  TurboTax's e-file system is shutdown for the season.  You would need to mail in your returns.  Make sure you sign your returns before you mail them & you should mail them so you can track them to make sure they reached the IRS & State.

How do I switch from "E-File" to "File by Mail" in TurboTax Online?
