No you cannot e-file a 2017 return. If you are trying to use the current online software for a 2017 return, STOP. The online software is only for 2018. Clear it and start over later when you are ready to file for 2018. If you use the online software for 2017 you will have a real mess to clean up.

Remember to prepare your state return as well—if you live in a state that has a state income tax.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS received the return.
Note: The desktop software you need to prepare the prior year return must be installed/downloaded to a full PC or Mac. It cannot be used on a mobile device.
