Hi Meagan,
Welcome to Ice In Space
The answer depends on a number of things.
The setting circles on the telescope are right ascension and declination.
These can only be useful if you have the telescope properly polar aligned from the start, (pointing at South Celestial Pole).
Then you can use them to find objects that are at fixed RA / Dec locations.
However, planets move about and they do not have fixed RA Dec.
So the co-ordinates do change over time.
I found when starting, the best way to find the locations of planets was by use of monthly star maps (can be downloaded for free from several sites) which pictorially show the bright stars in a region and indicate where the planets are from there.
Jupiter is easily observable at the moment. It is the brightest object (other than moon) each night and close to Orion (last time I checked).
Perhaps if you line that up, check your co-ordinates from the book, for comparison to your telescope setting circles.
Hope this helps
