Digital Photography WOOHOO category

Is there a plugin that helps delete Digital Photography WOOHOO category from my WP site? Everywhere I look from my Dashboard, I cannot find the function that would do it for me? (screenshot below if someone would pinpoint it out for me)

What you do mean?
Do you want to delete a category from your WP installation?

Go to posts => categories.

You will see a list of categories. You can delete whatever category you want to delete.
