Yeah, while cold the level will always be above the "line" on the dipstick, once warmed up it should drop. But I guess in your case there is just some extra fluid in there.
No real damage can happen aslong as its not super overfilled by like 1-2 quarts or more. It might be overfull my .5-1 quarts to cause some small bubbles. You can stick a tube down the fill tube and suck some out if you want.
