I'm not sure if you're talking about carving or skidded turns, but since others already talked about skidded turns, I'll do a quicky post on carving here.
So just start off slowly and ease into it, but don't be frustrated if it doesn't work out perfectly right away, it's a tricky skill to really master.
It sounds like right now you might be digging your edge in too much (hard to tell without video, but it's an educated guess). There's an exercise called 'gas pedals' which you might want to try out.
Basically think of your feet as the gas pedals of a car and your back foot always follows after the front foot. So just like in a car, you don't slam your feet down on the gas to go right? You gradually step into it. That's what you want to do for carving.
So to carve toeside, you'd start by gently applying pressure to your toeside edge with your front foot, your back foot would follow, then only increase the pressure to your toeside IF you want to increase how much you turn. Same goes for heelside turns except you gradually take your foot off the pedal.
You don't need to apply much pressure to carve. Just gentle, gradually applied pressure is enough to ride on that edge and carve and only increase the pressure if you want to turn more sharply.
Now as far as being able to carve while turning sharply, that's going to be a tricky skill to perfect. I know pro level riders who still suck at carving, so don't feel bad because tight, sharp carves take time.
For now though, you can work on and get more comfortable with doing mellow carves and just gently riding that edge to get a feel for how you ride when you're just on your edge and gradually progress to sharper carves with more practice as you get more comfortable with riding that edge and controlling edge pressure.
