Was the 2013 return prepared with Online TurboTax? If you used desktop software (CD/download), it would not be in an online account.
To
get a list of your User IDs and recover account access, you can use the
tool at the link below. Try using your phone number first.
NOTE: Before running the
account recovery tool below, log out of all Intuit accounts including
this user forum, or you might end up in a loop. Then clear your browser
Internet cache, close your browser, then reopen it, and go to the link
below. You may wish to copy this link so you can paste it into the new browser session.

If
still no luck after running that on your phone number, User ID, or email
address, then run the tool yet again, but this time choose the
small blue link that says "Try something else", and it will look you up by SSN and other parameters.
Once
you find the 2013 return, access might be locked until you pay for a 2016 upgrade to PLUS. If it is, we can
tell you how to do that.
