I've kept fish for years. Having more filtration than needed won't hurt a thing. Although it will set up a current in your tank that some species might not care for.
50gph filter is fine. Just don't use a 50gph pump to go with it. If you get a pump, try to get a variable one. Even if it isn't variable you can buy a sliding potentiometer to control its power input, and therefore its pumping speed. I have no idea what gph you would need for a pump on a 20gal tank, but it's probably some fraction of 20.

Why do you need a filter?
