Dear @Jonathan Hribar,

Welcome to Microsoft Q&A forum.   

Based on the information you provided, it appears you are unable to recover OneDrive and SharePoint data and those are unable to find in both recycle bin and version history.  

Since you mentioned that it is not in the recycle bin, please also check the second-stage recycle bin. You can find it the option at the bottom of the Recycle Bin page, select second-stage recycle bin.  

Please note:  

For SharePoint site, only the site administrator can access the second-stage recycle bin. If you do not have the necessary permissions, please contact your IT support team for assistance.  

For OneDrive, you must be the owner of the OneDrive or added as site administrator to access the second-stage recycle bin.
