Code required 20a to your kitchen, so you "ought" to be okay; but it is
prudent to check. You should have #12 wire and a 20a breaker. If you can't
confirm that, go back to a 15a outlet.

As a practical matter, what do you want a 20a outlet for? Except for a few
large tools, I don't think I have ever seen a 20a plug.
