Should be fine.
In beers you don't plan on aging for months or years, the consequences of not chilling fast enough are purely cosmetic; your beer will get "chill haze" when you put the bottles in the fridge.
Pitching too warm can lead to slow yeast starts and off flavors, but there are lots of other variables you're probably not controlling yet which will have a bigger impact, so, yeah... pitch cooler next time, but don't sweat it this time, you're probably fine.
The one thing you should do is take another hydrometer sample before you bottle. At 1.020, it's entirely possible the yeasties are still slowly chewing away at your wort; you wanna be sure they're really all the way done, as demonstrated by two identical hydrometer readings a few days apart, before you bottle, otherwise, you'll get over-carbonated beers.
