You will need to be careful not to make any changes to your return once you are in the already filed return, but you can use the following steps to get in the return and review any information that you would like to review.
- Log
in to your TurboTax Online account
- Click
on Taxes, and then click
on My Tax Timeline
- Locate
your 2016 tax return on that page
- Find
"Some things you can do" under your 2016 tax return
information
- Choose Add a
State (you don't actually add one; that's just to get the return to
open up.)
