My tax return is stuck on in progress, my 2021 and 2020 notice of assmentment numbers to access my current file keeps saying "incorrect" I can't delete my current return.

The NETFILE Access code is not mandatory, so you can just leave that blank if your code is not working.

If this is the only return in your account, you’ll need to start a new return before you can delete your existing one. To start a new return, select “Start a New Return” from under “My Returns”. Once you have started your new return, you can select “View All Tax Returns” from under “My Returns” and delete the unwanted return by clicking the small Trash Can 🗑️ next to it (or “Delete” under the return name).
