Upgraded Norton now files missing on PC

Prior to upgrading I had turbo tax from 2005 - 2023 already installed on my PC - no issues at all - upgraded to Norton™ 360 with LifeLock™ Advantage - and all my files are missing or moved to dropbox and recycle bin. Called Norton they blamed it on Turbo Tax - called Turbo Tax went through the whole computer and the only admin permissions were to Norton and my files are still missing. Norton wont escalate but said I could PAY them to have the Norton/turbo tax department fix it? What in the world is happening any help suggestions? HELP
