On your W-2, Box 14,
these entries are generally a catch-all for items where there is no other
place to put them.
Some of these
entries are relevant more to the employer and you, not always to the IRS.
You should list the
entries exactly as you see them and if there are no codes and you know what the
entries are for, you can choose what they are from the drop-down box.
If you don't know
what they relate to, you can use Other - not on
above list. TurboTax will be able to know how it impacts your
return.
