Yes, but not with Online TurboTax.
Online TurboTax is currently for filing 2016 returns. A 2015
return can only be prepared in 2015 desktop software (CD/download).
The 2015 return cannot be efiled; it has to be printed, signed, and
mailed.
Had you started a 2015 return prior to the online
shutdown in October? If so you can download your *.tax2015 data file
from your 2015 Tax Timeline and continue it in the desktop software.
Desktop
software can be purchased from TurboTax at the site below. Or you may
be able to find it at a discount at a reputable authorized retailer like
Amazon.

If
you had already paid for your 2015 online return prior to the shutdown,
then TurboTax Support should furnish you the download.
