I can’t find my Home Screen on my ipad

You can find information and guidance about organising and controlling your iPad Home Screen(s) here:

Use the App Library and Home Screen to organize your iPad apps - Apple Support

The Home screen can be summoned from Apps simply by swiping-up from the bottom edge to the centre of the screen - and pausing briefly - before lifting your finger from the screen. If your iPad has a physical Home Button, you can click the button twice to show the Home Screen.

Did you swipe left or right on the Home Screen to see your first screen?

You should see a couple of dots on the bottom of the scree, indicating which home screen is shown at the moment.
