Delete/Unsubscribe US Holidays Calendar!?

How do I Delete/Unsubscribe US Holidays Calendar!? I’m on the newest iPhone with iOS 13.7. I was able to delete it from my iMac but can’t delete from iPhone. All o can do is turn it off but can’t fully remove it!? In older iOS I found online in accounts/passwords settings of iPhone was able to see “subscribed calendars” and remove from there, but not on iOS 13...
