On my W2 I have an item in Box 14 labeled AZ SDI. In the category drop-down, there are many other states' SDI's listed, but none for Arizona. How should I categorize it?

I'm continuously frustrated by TurboTax asking for "categories" on these and other items where no categories exist on the actual forms (in this case on the W-2 in box 14). Does it actually matter to the IRS or state tax agencies what categories I put? Are these actually entered on the tax forms I submit?
