Planets don't get marked on paper star charts, for obvious reasons. This is where the electronic star charts are super useful as they can show any object in the sky that moves such as planets, comets, satellites, etc. There are many electronic apps in the market. I use one called StarSeek because I use it to drive my telescope. But I can use it anytime as an atlas to star hop around the sky. You can pick up cheap versions of this for around $10, and you will find all the planets in no time using one.
The outer planets can spend months and years in the same constellation, they move quite slowly. But even Pluto can be seen to move from 1 night to the next across the background stars in a telescope's field of view.
Once you have found these guys for the first time, you will locate them quick and easy after that. What makes Uranus and Neptune stand out against the star field is their colour. As I said, even in bino's they both have a green/blue appearance, but even more so in a telescope. Just scan around the area you think they are in with a lower power, looking for a green 'star'. Once you find one, up the magnification and the star might look like a small disk instead of a point of light, then as Borat would say, Ah success.
The key is having the electronic atlas to start with that shows you where the planets are. Star hopping to the right place then is much easier. Good luck
