welcome to the forum. filtering for places in the Explore page on the website is a common point of confusion for new users. instead of filtering for places using the Location input box next to the taxon input box, click on the Filters button, then More Filters, then use the Place input box in the More Filters form to look for your place.
the Location and Place filter inputs operate differently (i won’t get into it much except to say you can search the forum for many old posts on this topic), and there’s a reason that the Location filter box exists, but the bottom line is that you should probably use the Place filter box first and then resort to the Location filter only if you don’t get what you need from the Place filter.
