cannot get out of itune icon with usb plug

Good morning, Conmare.
It looks like your iPad has slipped into Recovery Mode for some reason. That indicates something's happened and you'll need to reinstall the iOS. I'll be glad to help with this.
If you see the Connect to iTunes screen on your iPhone, iPad, or iPod touch
Connect your iPad using the lightning cable that came with your iPad to a computer that has iTunes installed on it and see if iTunes responds. If it does, that's great! Just follow the prompts.
If iTunes doesn't respond, disconnect the iPad, turn the iPad off using the sleep/wake (power) button. Once it's off, press and hold the Home button and reconnect the iPad to the cable. Don't release the Home button until iTunes responds. Again, if it does, follow the prompts.
​Once iTunes has reinstalled the iOS again, you can use a recent backup you've made to set up your iPad again. If there aren't any recent backups, set it up as a new iPad and sign into iTunes & App Store and iCloud. You can sync the information that's available. Anything else, I'm afraid, is lost.

Have a good day!
