Edited to remove the original post, as @TomYoung is absolutely correct, the taxes withheld should be incorporated into your W-2. To the source of your confusion, if your employer is already withholding 22%, they may not have withheld extra if this compensation is considered a bonus. Bonuses below $1 million are taxed at 22% if your employer is using the flat rate of withholding.
