Dear Bruce D Silverstein,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
- May I know its OneDrive for personal or office 365 OneDrive? may I know what is your license?
How does Microsoft storage work? - Microsoft Support

for office 365 work or school user's storage space in the Microsoft 365 admin center.
1. Sign in to https://admin.microsoft.com as a global or SharePoint admin. (If you see a message that you don't have permission to access the page, you don't have Microsoft 365 admin permissions in your organization.)
2. In the left pane, select Users > Active users.
3. Select the user.
4. Select the OneDrive tab.
5. Under Storage used click Edit.
6. Select the Maximum storage for this user option, and type the storage limit that you want to use.
7. Click Save.

- When a user has filled their 5 TB of OneDrive storage to at least 90% capacity, Microsoft will increase your default storage space in OneDrive to up to 25 TB per user (admins may set a lower per-user limit if they want to). The storage limit will be reset to 5 TB if OneDrive storage utilization drops below 90% of the 5 TB capacity.
- For any user that reaches at least 90% capacity of their 25 TB of OneDrive storage, additional cloud storage will be provided as 25 TB SharePoint team sites to individual users. For more information and assistance, contact Microsoft Support.
- Admins can check for OneDrive eligibility beyond 5 TB via Check OneDrive site eligibility for increased storage.
Your understanding and patience will be highly appreciated.
If there is any misunderstanding, please feel free to correct me.
Have a nice day!
Best regards,
