Level 15

Box 14 is just informational.  Unless the information has a direct impact on the return that has not already been reflected on the W-2, there is no need to have a separate item for it.  "Other" is fine.

So assuming all of the other boxes on the W-2 have the proper numbers, there is no need to even enter Box 14 if it doesn't require an additional entry elsewhere on the tax return.
