Assuming you went to the Campaign Details Page (click View Details from the My Campaigns page), then clicked on Campaign Settings link on the left-hand menu, and scrolled down to the Character Sheet Template drop down menu and selected a Template (there is one for Dungeons & Dragons 5th Ed.), and then clicked Save Changes. Once you've done that you would have a 5th edition D&D character sheet for your players. If you did do that, you'd still have a character sheet for your players, but it would be generic and you'd need to build everything yourself for the attributes and abilities.
