Not sure if I will be helpful since its been a while since I played any story missions and been out of the loop. Anyways first off, which one are you talking about? if I remember correctly the story missions for TDB and HoW are in bounties form, so turning them in the person whomever you got it from, should be it..
On one of the pads with the elders you can pick up 'abandoned' quests. It's giving we quests and XP for the old missions though.
