Here's how to download/print a 2015 return:
Log in and in the top left corner click on MY TURBOTAX, then in the dropdown choose MY TAX TIMELINE.
If the only thing that is evident is the 2016 info, then on a line underneath that look for a faint blue link in the lower right corner that says "Load Tax Timeline", and then it should display other years.
In the 2015 Timeline, scroll to a section called "Some things you can do."
There should be a link for "Download/print the PDF."
If there is no evidence of a 2015 return at all, we can tell you how to look for multiple accounts.
