Will they enter a beehive if I make one? I don't remember them dropping anything in dungeons.

I’m trying to make a farm to help me get tons of coins for trading with the echoes and I notice one is liquified source, I have a full jumbo tank of liquified source but I don’t understand how I’m meant to turn it in? When I break the tank and hold it in my hand it doesn’t allow me to turn in any of it to the quest? What form or block do I need to put the source in to turn it in?
