LOL .. This a joke?
if not -- there was not one leaf you should have removed. topping is fine, because you only lose 1 node or 1.5 nodes of growth, typically. That won't set an autoflower back too much, but is a net-loss of some minimal amount. Plant training is all you need to do to level out a canopy with an autoflower. It won't grow large enough to need anything elaborate.
it will do fine, health-wise but you've reduced growth potential for the next couple weeks as new leaves fill in. Tiny, new leaves don't do much photosynthesis until they mature a bit. read the 'to defoliate or not' in dr photon's corner of cocoforcannabis com
