The option is there, just not where you are looking for it.
On the start/splash page of the downloaded version you will find "Continue Your 2023 Tax Return" and then your returns listed on tiles.
Below that there are options in blue to start a new return or continue from online.
Below that there are grey buttons where the amend a return is available.
If your return has already been opened, you will not be able to find these buttons; close your return and the splash page will appear.
