Can I go back and enter missing information on the 2018 return I'm still working on?

Forgot to enter the Adjusted Cost Base on the first few entries in Capital Gains dispositions. Not sure how to go back to those entries and enter the missing information.

You can use the left hand navigation menu to return to the section where you entered the information originally.

If you are using a mobile device or a narrow screen, you may need to click the menu icon at the top left to open up the navigation menu.

Once there, you will be able to add, amend, or delete information previously entered.
