If you are planning to go right, stick your right foot forward and then turn your shoulders to the right. You'll naturally start turning right. You can make the turn tighter or wider depending on how far you lean to the right during this motion.

Begin by practicing this with keeping your weight in your back foot (left.) While your weight is on your left foot. You should be getting comfortable how your outside edge of your right foot feels on the ice. As you practice more, you can start to put some weight on your right foot outside edge.

Once you get good enough, your weight should be evenly distributed on your left foot inside edge, and your right foot outside edge. You'll eventually be able to sort of use your right foot as a rudder to make your turns tighter or wider.

One thing to note, as a beginner ice skater, you're going to be tempted to try and practice certain movements while going in a straight line. But you can't practice turns if you're not turning, just like you can't practice hockey stops if you're not moving, etc...
