You only enter the information from the 1099-B form. The supplemental information is for your records. You may need it to calculate your adjusted cost basis. Since the gain on that stock sale was included as income on your W-2, to avoid double taxation:
- You will need to change the stock basis on the date of the sale, to the price on the date of sale.
- The result is zero gain or a minor loss due to brokers commission/fees.
- The IRS will expect to see that information on your tax return.
To enter your 1099-B form, see Where do I enter a 1099-B?
