Rockstar has explained how the HUD elements work in Red Dead Redemption 2. Unlike some games that flood the screen with numerous waypoints and objective-markers, Red Dead Redemption 2's HUD is minimal by default.

The standard setup displays a small mini-map in the bottom-left corner of the screen. This shows you important objectives and other information. Alternatively, you can make the mini-map larger to get a closer look. If you'd prefer not to see it at all, you can also turn it off entirely (just like you could in 2010's Red Dead Redemption).
