In the main Box 14 of the W-2 is a "memo" box where your employer attempts to communicate something to you. Generally, entering a Box 14 amount, or not entering it, doesn't affect your income tax returns. There are a few exception to this, but an RSU amount in this box is not one of them.
Your employer is simply telling you that amount is included in Box 1 of your W-2. It's important to you if you sell any stock as your per share basis in the stock is: Box 14 dollar amount divided by the GROSS number of shares vested.
