If you have transferred 2016 data into a 2017 return, the fastest way to do this would be to go to the Return
Manager (under Tools) and start your return over again.
If you've logged into your account and only see your 2016 return, please log out and log back in on the 2017 Turbo Tax website. There you can start a fresh 2017 return.
