Then you need the W2s and any 1099 and your info for 2011 and 2015 (not from 2010 or 2014)
Online is only for the current year so you have to buy the Desktop CD/Download program here https://turbotax.intuit.com/personal-taxes/past-years-products/
Turbo Tax only sells the last 3 years so they only have 2013 and newer. And you only have 3 years to file for a refund so it's too late to get one from 2011.
