Issues with OneDrive when migrating files from one computer to another

[LizParkerWE]

I have just bought a new laptop with Windows 11 installed. I have tried to migrate files and folders from my old laptop initially using a a separate hard drive which caused problems then I transferred them directly from the C Drive to the new laptop using a usb flash drive. In the first instance I was unaware that OneDrive was involved in this process so I ended up with my free OneDrive allocation used up. At that point I unlinked it. I do not wish to use OneDrive at all.

My C drive is now a complete mess. Can you tell me please why most of the file extensions in my Documents contain C:\Users\lpark\OneDrive ?

I appreciate that I have a problem in that I don't understand where I went wrong. My old laptop is running Windows 10 vers.21H2.  Also, my knowledge of terminology is sketchy so I will need plain English please.

Do I need to get rid of the OneDrive file extensions? If so, how do I do it and if not is it ok to leave them as they are.

Did you ever get any kind of answer for this?  I'm having the exact same problem.  I've called my support department 4 times to no avail, (none of them were on Win 11), and  I'm on 5 weeks of dealing with this.  Any help would be appreciated from anyone.
