Box turtles are automatically obscured across a lot of their range, so they won’t appear in most searches of small areas on the Explore page. https://www.inaturalist.org/pages/help#placeindex
There’s an open feature request to display true coordinates on the Explore page when they’re your own observations and when other users have trusted you to view the true coordinates. https://forum.inaturalist.org/t/view-true-locations-on-maps-for-observations-with-trusted-hidden-coordinates/2568
(also when I go to your first link, no box turtles appear, as it should be:)
