October 15, 2018 was the last day for e-filing your 2017 returns. If you completely finished and paid the fees for your return, you still have the option to print and mail it to the IRS. If you started the return, but didn't quite finish, you can purchase the 2017 TurboTax CD/Download software to complete the return on your computer.
