I accidentally broke this knob by forcing it to continue turning and now it is disconnected from the mechanism that makes the shades turn. Where do I find this?

The closest match we have to this type of hardware is the Pella 70-165 or 70-150S. Compare both with your old part. If neither seem right, I advise you contact a Pella dealer for assistance.
