Hi,
welcome to OSM! I looks like you tried to add a bus route here. Unfortunately the way you did it is not quite right - we can't add a new line on top of the map, but we need to add a relation that makes use of existing ways.
The tagging scheme is described here: 
https://wiki.openstreetmap.org/wiki/Tag:route%3Dbus

The best way to learn how its done is to look at existing bus routes, they should be easy to find.

If you have questions, the best place to ask for assistance is the OSM community forum.
