No. You need the 2015 Desktop program to open a .tax2015 File. Turbo Tax is only good for 1 year and is not backwards compatible.
If you used Online, Call in and ask for the Desktop program. Contact Customer Service 5am-5pm Pacific M-F
https://support.turbotax.intuit.com/contact/ After you get the program installed the first thing to do before you open your tax return is to update the program and install any state programs you had. Then open your file. So you first might need to start a fake return to be able to download the state program (go to File-New Tax Return).
Then go to FILE -Open and find your return.
