Don't know if this will help any Turbo Tax users but one Quicken user found them......
What I found was that my Quicken Data files ended up in the One-drive Recycle bin. Not sure how, but I found them there. I placed the files back onto the laptop and brought the files into Quicken and now have all my data back.
Your tax return file ends in .tax2018, .tax2019, .tax2020 etc. Search your computer for it. Check the Recycle Bin or Trash. Check in One Drive, etc. it should be in your Documents then in the Turbo Tax folder. Check your backups.
