Are you sure? When vested RSU's are sold to cover taxes, the value of the shares is considered "compensation" and is included in your W-2 Box 1, and the amount of the taxes paid with the withheld shares is included in your Box 2, federal taxes withheld. Why do you think your W-2 didn't include your RSU withholding?
Also, your 1099-B that reported that sale should have a net capital gain/loss of zero or near-zero, since the shares were sold the same day you received them. (The cost basis and the sale proceeds should be basically the same.) You should report the 1099-B on your tax return but the effect on your taxes should be nil.
