Dear TerriL001,
I'm very sorry for the late reply as I had a day off.
Since yesterday we have heard good news, OneNote support team has posted a fixed thread in the community, you can try using OneNote again, if you still have problems, you can continue to post in the community, you can refer to the thread below:
OneNote sync failure error code:0xE00009C8 bb0ur - Microsoft Community
[From the OneNote team] OneNote Sync Issue Update - Microsoft Community
I hope this gives you some clear direction and wish you all the best in using it.
Best wishes
