Hey, @kdkclickchick. Welcome to the Photoshop Community. I'll need more info to help you figure this out.
Please share the screenshots & system info from Photoshop Help > System info > Copy & paste into a text document > upload & attach here.
The description is not sufficient at this point. Do you wish to position the crop at a specific position on your image?
If you enable 'Use Classic mode' for the Crop tool, you'll be able to drag around/move the Crop overlay on your image.

Let me know if this helps. Thanks!
