I wanted to edit my return before filing, but I can't see an edit button. anyone?

What information are you trying to edit? If you have already certified your return, you won't be able to change any personal information.

Thank you for choosing TurboTax.

Before reviewing and submitting tax forms, how can I edit all details from the beginning? I did not have all my self-employment info when I first started mine and my partners returns (file together). I can not seem to get to self-employment expenses to edit at all.
