You are using PowerPoint Presenter View with your laptop and an external screen. You want the slides to show on the external screen and Presenter View on your laptop screen so you can see your notes and look at the webcam. But PowerPoint insists on putting the slides on the laptop and Presenter View on the external screen.
In PowerPoint, go to the Slide Show ribbon. In the Monitors section you set which monitor displays the Slide Show (not which monitor displays Presenter View). Use the drop-down list to select your external monitor.
Now when you start the Slide Show, the slides will appear on the external monitor and Presenter View will display on your laptop screen.
Here’s a video that demonstrates this solution.
