There is a proposed tag for lanes:both_ways=* <https://wiki.openstreetmap.org/wiki/Proposed_features/Suffix_both_ways> that I use for those. The handy JOSM Turn Lanes plugin supports this, which you can see in the second screencap on their repo <https://github.com/JOSM/turnlanes-tagging>. Mapbox has done a lot of turn lane mapping around the US and offer some helpful tips here <https://www.mapbox.com/blog/turn-lanes-mapping/> and here <https://www.mapbox.com/blog/la-turn-lanes-map/>.
