Hi There,
Thank you for your question. Using the navigation bar on the left of your screen click on the 'Review' tab and there should be a drop-down list that opens. You should see a "Canada Workers Benefit" tab. If you click on that tab, it should open a window there should be a screen that says "Do you want to claim the Canada workers benefit" with a yes or no option. This should adjust your expected refund amount.
