Partial New York State Income

Hello, I have partial income (RSU related) attributed to New York State.  However, in my received W2, it's not the partial amount but ALL the federal income (Box 1) that is reflected in my New York State income (Box 16), is this right and what I should do in my tax filing?  Currently, I know the total amount of my NYS related income which is about $30K, but am not sure about the reportable wage portion of the $30K, or should I file income based on $30K?  Thanks for your help!
