I ended up deleting Windows Office Compatibility.rtf in FontCollections in Library. All my TextEdit documents that were previously rich text are now plain text. I thought going back in the Time Machine and retrieving it would work. When I did, I opened the Windows Office Compatibility.rtf document. It was a TextEdit file in the plain text...
TextEdit Files went from Rich text to Plain text
