I need to file last years taxes

[jerry2000 · Accepted solution]

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:

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.

Go to this TurboTax website to purchase and download one of the tax year 2015 desktop editions - https://turbotax.intuit.com/personal-taxes/past-years-products/

A tax year 2015 return can only be printed and mailed, it cannot be e-filed.

If you started a 2015 tax return using the online editions and need to complete the return, then see this TurboTax support FAQ for the procedure - https://ttlc.intuit.com/questions/2559403-how-do-i-finish-a-prior-year-return-that-i-started-in-turb...
