To edit details about the grant, including the strike price, right-click the investment name in the Portfolio Manager, and then click Investment Details.
If you are exercising and holding, you now own shares instead of options. You should enter those shares as a stock purchase in the Portfolio Manager. To record the stock purchase, click the account where you hold the shares (not your stock option account), and then enter the stock purchase as you would enter any other stock purchase. In the Price box, enter the strike price, not the market price.
