Hi @Kevin W ,
Did you mean you want to remove the folder in SharePoint? Did the folder save in local or web?
Did you get any error messages when you trying to delete it?
As far as I know OneDrive sync folders from web to local, I suggest you go to web location and check if you can find the folder you want to remove.
If my understanding is incorrect, I suggest you be a bit more precise to explain your problem or you can upload a screenshot so that I can get more accurate solutions to this problem. I’m glad to help and follow up your reply.
