Quest items show up at random when you're charging rooms while visiting, so if you wait long enough, the quest might move past the problem.

Items accumulated before the quest opens don't seem to count (I've had as many as 3 of a CI but had to find a new one), but any that come in after the quest opens--through playing the game, visiting, or gifted--count toward completion of the quest.

For giftable items that you already had before the quest opened, you may be able to make a deal with a friend; you gift it to them, they gift it back to you. That would count toward the quest.
