did you file after 4/18/2022 without a timely extension. the penalty for late filing and late payment after 4//18 would be 5% a month or a fraction thereof. this is unlikely since you got the penalty notice so soon.
so there is something else going on. we can't see the penalty notice so you may want to contact
