1099B adjustments for stocks that are represented in my W-2

[Tammiefosdick]

My stock grants were done through payroll deduction. They’re reflective in my earnings on my W-2. I received a 1099B how do I adjust to not be attached twice? Would the adjustment be with the total proceeds are? My payroll the total proceeds is what I was taxed on?

Your cost basis is the amount you paid (if anything) plus the amount that was included in your income and reported in Box 1 of your W-2.  That amount may or may not be the same as the proceeds.  Even if sold the same day there could be small in the price used to determine and the price the stock was sold at.
