No, you will need to
file a return, or amend your 2015 return to include the W-2s for
2015. Your W-2 from 2016 will be entered in your 2016 tax
return. You can only use Turbotax Online to file for the current
year (2016) taxes, and not for any other year.
If you would like to
use TurboTax for any other year you will need to purchase the Desktop Version
for the specific year for which you need to file a return. You can purchase the
Desktop version at this link:
