when I drag something to the timeline it is always present from the beginning of the animation. I want it to appear later in the animation and have no idea how to do this. Can you please help?
You need to set the "Display" to "Off" from the Properties Panel, and then set it to "On" wherever you want it to become visible.
You need to select the element and then select the display on or off. Click on the diamond at the beginning, then choose display on or off. Then move the playhead where you want it to do the opposite.
If you mess up you can always choose display always again and start over.
thanks for the answer, helped out
