You are so kind to make these suggestions. I followed the one with the guy who found his using admin credentials. Also tried opening as admin - didn't make a difference. Could not find any folder that was user/admin. I have checked the show hidden files. Also worked in the command prompt to find any admin folder. I have no idea why I have no admin folder. Another mystery. I have accepted that this file is lost and started over. I started a new return and am half way to where I was before. I saved the file with a different name just in case this one reappeared but it's nowhere to be found. Also I am working on a microsoft surface windows 10 and checked my onedrive as someone suggested. No luck. Found some pictures I thought I had lost forever from 5 years ago - so thank you for that! Moving on with life now.. no explanation for this at all. I've used tt for years. Never had this happen before.
