Hi there ReidyFox,
From what we can tell, the built-in keyboard on your iPad isn't responding as expected when typing. We're glad you're here, and we'd like to learn more to see how we can help.
To begin, do you have any third-party keyboards installed? You can check by going to Settings > General > Keyboard > Keyboards. Learn more here:
Add or change keyboards on iPad
Next, does restarting your iPad seem to help, even if only temporarily? Have a look at this support article to learn how to restart iPad:
Restart your iPad
Also, do you notice this delay when typing in specific apps? If so, which ones? Does there appear to be an issue with the screen of your iPad not responding to your touch at all, or does it seem to be isolated to the on-screen keyboard only? Which iPadOS version is listed in Settings > General > About? Send over these details, and we'll take a closer look from there.
Take care.
