Box 14 is missing info; well, what does it want?

I'm in the PERSONAL | Personal Income section. I had to enter a couple lines from box 14 on my W-2. That brought me to this page. TurboTax copied the description and amount from the previous page. But now TurboTax wants me to add a category. And TT adds, "If you need to add a category, select Other (not classified)"

 

Huh? I don't know what TT is talking about. My W-2 only lists a description and amount. There is nothing at all there about a category. What am I supposed to do in this case?
