Based on your description, I have some questions as below.
Do you use OneDrive for personal or OneDrive for work or school?
Is your OneDrive synced to your computer?
If so, please check the Recycle Bin (on a PC) or Trash (on a Mac).
>Restoring 30 days is not enough.
<<Do you mean that you would like to restore files that are deleted over 30 days?
Please make sure you are signed in with the correct Microsoft account and to check if the storage space of your OneDrive is full.
Besides, you may refer to this article "Restore deleted items from the site collection recycle bin" to see if you could restore files from second-stage recycle bin.
