Get your taxes done using TurboTax

When you exercise and sell NQSOs, the broker does not report the correct stock basis, which is the value of the stock on the date of exercise.  As a result, (and as you seem to be aware) you have to adjust the cost basis reported on the 1099-B.  If you imported your Form 1099-B, you may not have the option to adjust the cost basis.  If that is the case, you will need to delete your Form 1099-B and enter it manually.  You will then have the option to adjust the cost basis to reflect the amount that was included in your income.
