First enter your Capital Gains for the year. Then go to the Losses section & check off "Net Capital Loss Carry Forward". Continue until you get to that page. Enter your capital losses from previous years and then click Continue to get to the page where you can enter how much of the loss carry forward you want to use for the current year.
You can only use a maximum of whatever your taxable capital gains are for the year. Remember that only 50% of your total capital gains are taxable, and that's reduced by any losses that you had in the current year (before any previous year's losses are applied).
