Can't get OneDrive with all my data on new computer

I bought a new laptop recently and have been working to set it up with everything my old computer has. I love my old laptop, but it is five years old and I worry about failure and losing everything. Because of that fear, I have used OneDrive heavily. Anyway, when there was a pre-BlackFriday sale, I purchased a new laptop. I got OneNote to come over with my folders, but I can't get the OneDrive synced. I have researched online and have tried sharing and other suggestions, and nothing works. How can I get my new computer to use the same OneDrive?
