You can only buy the download for prior years. You have to buy a separate program for each year. They only sell the last 3 years. You need a full Windows or Mac computer to install it on. Buy the download here

You have to print and mail prior year returns. 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. Don’t forget state.

Important! Mail Federal and State in separate envelopes and mail each year in separate envelopes.

If you are getting a refund, there is not a penalty for filing past the deadline. You have 3 years to file for a refund. If you owe taxes, the interest/penalties will be calculated by the IRS based on how much you owe and when they receive your return and payment. The IRS will bill you for this; it will not be calculated by TurboTax.

What are you trying to do?

"I did file last year but am on disability and I didnt have to."

If in fact you filed "last year" that would have been for 2017, so what are you trying to do now with a 2017 return?    Are you trying to amend it?

You cannot ever change the year on the tax software.  Each year has it own software written specifically for the tax laws in effect for that tax year.  The current online software can only be used for a 2018 tax return  -- it cannot  be changed to 2016 or 2017.

If you need to file for a different year you have to purchase and download the desktop software for the earlier year and then print sign and mail the return.
