As to a Citation, you can buy a copy of the handbook from any dealer for a reasonably modest amount of money ($25 or so, I thínk). Therein you can find a generic example of a load sheet and directions on how to work a loading problem.
As pointed out, load sheets are specific to aircraft. Even when you have two aircraft with exactly the same interior fit then they will usually have slightly different weights and C.G. locations. So once you have the load sheet you still need two more data to work the problem.
