Moving files out of unlinked, unsynced and disabled onedrive

I am out of storage space on my PC -Windows 11 and get reminders of that everyday. To help solve that problem I would like to move MyDocuments (a huge file) to Drive D.

Here is the potential problem. I unlinked, unsynced and removed OneDrive in 2020, or so I thought. I still see the OneDrive symbol in Microsoft Explorer above the line from Drive C and other drives. Most of my files are accessible in Drive C, but not MyDocuments, Desktop, and some others. They can only be opened thru OneDrive. This always puzzled me, but since all my files are accessible to me, I haven't worried about it. Now I'm concerned that OneDrive still has its tentacles around some of my files. MyDocuments and Desktop are being updated, but my files in the cloud are seriously out of date. What does that tell me? If they are still tied to OneDrive somehow, does that complicate the removal of those files to Drive D?
