Oh, I thought you already got the talisman. Must have been thinking of someone else. Anyway, it is possible you received a needed quest item before the quest became active. And now that the quest is active, you'll have to get it again. Happens sometimes.

Beware though: there is a nasty little trick in game wherein if you get the last of the 5 items for one of the quest collections, but by some other means than by tapping the quest and following the hints there to complete it, the pop-up message to complete the collection will say you "can" complete instead of you "must" complete. Completing by following the hints in the "can" message can leave your quest stuck so you will have to wait until you can get the item again and complete the collection again, this time by following the hints in the quest instead.

Hopefully that isn't the case this time...but it sounds like it could be.
