These are W2's from 2015. Why won't it let me file?

Uhmm.. could be because you're working on a 2016 income tax return?

If you want to do 2015 for free you can get the blank forms from the IRS and filll them out by hand.  Here are some blank forms & instructions for 2015

THEN FOR 2016:
You can still use your Online account to do this year's 2016 return but you will need to clear out your entries and start over for 2016.  Or abandon this online account and start a new one.

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.
