Hello.
Assuming you still have all of the data safely backed up, right?
The mistake here is that you should have turned off folders back up in Onedrive settings first, that would return all of the folders back to its path, and you shoudln't have to create your own desktop, documents folder, etc.
I assume Onedrive is uninstalled now? If so, Please type regedit in the search on the taskbar to launch registry editor, and go to this path, then take a screenshot and share in your reply.
