How do I change the tax year...mine says it is for 2016 but I need it for 2015

You can not change the tax year.

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 and install it on your own computer 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:

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.
