Generally, wrinkled leaves are a sign of underwatering. However, they can also occasionally be caused by overwatering, so we should first consider the conditions which led up to this point. Firstly, how long ago did you repot your jade? It’s a good idea to avoid watering right after transplanting, as this allows the plant’s roots to get properly established.
You mention that you don’t water much, which is good, generally. The important thing is to let the soil dry out completely between waterings, and to water deeply. Check if the trunk of the plant feels mushy at all. If so, this is a sign of rot (and overwatering).
How much direct sunlight does the plant get in the window? Too much direct sunlight could be drying out the plant faster than normal, especially in the dry winter air. Additionally, how cold does it get near the window at night? Jade plants don’t like to get below 50°F at night, and should be kept away from drafty, cold windows.
With all that in mind, it seems most likely that your plant is too dry. Water it deeply and let it dry out completely before doing so again in a couple weeks.
