I suggest you make sure there is no information in the following sections/forms :
- click Find (top right corner) --> type Employment expenses --> click Go
- click Find (top right corner) --> type Employment status --> click Go
- T2200 & TP-59 Conditions of Employment
- T777 & TP-80 Statement of Employment
After deleting all information from these sections/forms go back to the Personal Tax Profile section under My Info menu and answer No to Did you have expenses related to your employment?
