Three fingers won't work and I'm zoomed in on the lock screen

My iPhone X is stuck zoomed in on my lock screen! I have tried the three finger double tap and it doesn't do anything. I have tried holding down the power button to power it off but it doesn't do anything. I have tried to hold down the power button and the home button to reset it but it either doesn't do anything or it takes screenshots!!

I went to go onto iTunes to reset it however I need to have my phone unlocked to be able to do anything with it!!

It allows me to pull down my notifications and pull up my action centre but it won't let me open anything that I click on. I've tried calling the device and it rings but still has the zoomed in image of my lock screen!

I have held down the sleep/wake button and the volume down button but the slide to turn off option is not available because of the zoom.

I'm at a loss and really need some help!!
