Hi,
I believe the question you're looking for is in the Provincial section.
If you start at the beginning of the Provincial section, and you've selected Ontario as your province, you should see:
"In your personal tax profile, you told us you lived in Ontario".
If that's not the case, you can update your province of residence under Intro->"your" province of residence.
In the Provincial section, you'll be presented with questions that will help you apply for various Ontario tax credits.
