Can’t find my website to edit

I access WordPress through Turbify. They recently updated their site. I was able to find my way to the WordPress Dashboard but none of my pages are there. There are pages listed, but nothing is there. When I click on Master Slider there is not even a slide. How do I access my page info? I am not the one that built this site, I only edit it. I am not familiar with the “jargon”, so please keep your respond simple. Thanks!
