You may be missing the point here.
Typically, with a few exceptions, entering something in Box 14 has no effect at all on your income taxes. You can enter your RSU income as "other", or not enter it at all. Either way your tax calculation will be unchanged. The dollar amount is already included in Box 1, the number there is purely for your own information. That's why Box 14 is largely considered a "memo" box.
