It looks like your quiz is online in the 'Coasters and Theme Parks' category, which is the parent category for the sub-category that will give the TRIC credit.
When you save a quiz in an eligible category you get a message at the bottom of the TRIC page confirming that you'll get credit for it once the quiz is online.
Fifiona has it right; your quiz is not in the subcategory listed. I would recommend discussing the possibilities with your category editor if you still wish to get the quiz to work for the section you're aiming for, but this might not be a possibility since the quiz has already been played.
