A good place to start is here :- https://learnosm.org/en/beginner/id-editor/ this will give you an introduction to the iD editor. You can contact me if you need further help, (click on my name, to send a message).
What you want to do, in OSM terms, is add a ‘feature’ (a thing) at a location.
You need to find out what OSM uses (tags) that feature e.g. a school is tagged as “amenity=school”
and one way of finding these ‘features’ is to use the OSMwiki
amenity=school
On the top right corner of that page there is a search box .. type in there want you want to add and hopefully it will find it for you.
The editors, such as iD, have many things in them .. but not all. The OSMwiki also has many things .. a few more than the editors, and it is also more verbose than the editors. I prefer to use the OSMwiki as that gives me more information.
