You do not want to ignore it. If you do that, the IRS will assume you had a short term gain of $15,000. You have to enter the information on your Form 1099-B you received from your broker as reported. However, you will need to made an adjustment to the Cost Basis in the entry section so that your cost basis reflects both the strike price (the amount you paid to exercise the options) plus any additional amount you were tax on. For example: if you paid $10 per share, and the stock was trading at $15 per share, you would have had $5 of income added to your W-2 as taxable wages. Therefore, you adjusted cost basis is $15. If the shares purchased were then sold for $15.25, you would have a $0.25 gain.
Form 8949 is created by the program when you enter the sale of investments. After entering the transaction, you can view the form in "Forms" mode.
