Yes, if you think you used too much fertilizer you can remove some. Don't dig down and expose the roots or you will do more damage. If there are visible pellets remove some of them. I wouldn't prune it unless it gets too big for the space. Citrus trees don't usually get pruned except for size. It probably needs more light to produce fruit. They prefer full sun.
