How can I create a U-turn for routes in OSM?

Question

I am facing a problem when mapping a route in which the bus should make a U-turn at Rua A (Recanto dos Lagos) at coordinates 21°42'34.6"S 43°19'49.7"W, but the route follows another street (Rua Amaryllis) instead of returning. I tried adding a mini roundabout to the location, but that didn't solve the problem. Is there another way to try to make this return?
