I haven't lived in Seattle for a few years now. But it looks like it should be in the Rainier Valley neighborhood. However Rainier Valley was entered as place=suburb. Since Seattle doesn't have suburbs as defined by OSM, you could change it to place=neighborhood. https://www.openstreetmap.org/node/150959549#map=19/47.55254/-122.29089. Let me know if this seem right. If you do change it, it may take a couple of days before Nominatim catches up.
