Turbotax Online works only for current year (2016) taxes, and not for any other year.
If you want to use TurboTax for any other year you will need to purchase the Desktop Version for each year that you need to file. You can do that at this link:
http://shop.turbotax.intuit.com/personal-taxes/past-years-products.jsp
You can download the Forms and Instructions free from the IRS web site at this link:
http://www.irs.gov/app/picklist/list/priorFormPublication.html
In any event, you have to file the return by mail. Turbotax does not support e-file of prior year returns. Tip: If you prepare multiple years of prior returns, mail each one to the IRS in a separate envelope to be sure that each one is recognized as a separate tax return.

Thank you. I don't need the Deluxe package. I usually do 1040EZ online form. Can I get a cheaper version than the deluxe to be able to file my taxes?
No, there is no free version of Turbotax for prior years. As stated in the original answer, you can get the forms and instructions for free from the IRS web site.
