Julia, you most likely planted them just like you're supposed to. When I get the little bulblets forced to the surface, I do just like you did--poke them back down an inch or so. Its not fussy as long as they're covered-- thats good enough. Lily bulbs and little bulblets will level themselves even if they're crooked or sideways and if the get forced up, they will pull themselves back down to the level they want to be at.
When I looked at the pictures last night I thought: funny how Mother Nature works sometimes. Here you see the old main stem being separated and lifted harmlessly from the main bulb. And along with it the little bulblets got lifted out and farther away from the main bulb so they're on their own to form a clump. Ah, the marvels of nature at work!
