Problem with Migration Assistant

I'm trying to restore my MacBook Pro from a previous Time Machine backup, however; when I try to use Migration Assistant it says that I don't have enough storage, it shows that my Library (from the backup) has ~1.6 TB in files. I believe this is from OneDrive, I used files on demand so they did not actually take that much disk space but it still shows that amount of files on the backup. Is there a way to find the OneDrive backup and delete or remove it so that it doesn't try to restore it through Migration Assistant?
