Can I deduct RSU's value from the W-2' Wages, Tips, Other Comp in box 1?

The employer included the value of given Restricted Stock Units in Box 1 of the W-2 form (Wages, tips). This increases my income from 2018, but I did not have access to the RSU money. So, actually I did not receive the value shown on Box 1. I only receive my regular wages.
