Hi KallyKorn,
Welcome to Microsoft Community.
How did you delete out all documents, do you mean you delete them from OneDrive?
"when asked if wanted to restore autosaved documents", do you mean you tried to use the OneDrive restore feature? This site (Find lost or missing files in OneDrive - Microsoft Support) gives all the ways the find lost files in OneDrive. Note that if you purge the recycle bin in OneDrive, there's no way to recover it, including restore OneDrive.
If my understanding of your problem is not correct, please feel free to point out. Thank you for your understanding in advance.
Best Regards,
