You can complete your quest by playing through level 22 again. Make sure you kill all of the enemies before going through the victory portal.

If you don't complete the quest steps in order, you often have to repeat the quest to wrap up any loose ends. I had to re-run this same quest because I went through the exit before finding all three towers first.
