No, it won't adjust the W2. The W2 won't affect the Sched D or the 1099-B. You have a sequence of events. You have two separate events.

1. Someone has the right to the stock. When it vests, that's the date of FMV to payroll and to be taxed through payroll.

2. Someone sells stock. This is no different than any other sale. You might need to look up the basis by reference to the vesting and any sales expenses, like any other sale of stock.
