You can do 2016 either in the Online Self Employed version or buy the Desktop CD/Download Home & Business version. You can efile a current year return until Oct 16, 2017.
You can't do a prior year return online or efile it, but you can buy the Desktop Download versions for 2013-2015 from Turbo Tax here. Be sure to pick the right one, Windows or Mac....
