I've entered my Property Tax Relief refund and STAR refund in the section for Property Tax Relief and STAR Credit, but they are not reducing Form IT-196, Line 6. Why?

The number shown on Form IT-196, Line 6 is the gross property taxes paid per my Form 1098.  I had thought on my IT-296, the gross amount would need to be reduced by any relief, rebates, and refunds received.
