you would just copy the exact commands above into the text input box in the overpass turbo page, click the run button, click the export button, and then click the button to download a KML file. i wouldn’t expect that process to be any more difficult than the process you attempted yourself.
there’s some more information about the process at https://forum.inaturalist.org/t/how-to-import-a-place-from-openstreetmap-into-inaturalist-using-overpassturbo-web-based/41046.
