I'm sorry to hear that you're experiencing this issue. I'm happy to help.
I understand that you're having an issue with storage wherein Outlook keeps telling you that you have used up your data allowance even though you upgraded to Microsoft 365 Family with 1TB of storage and your account shows that you have barely used any space.
Sign out of all accounts in Outlook, then sign back in using only the Microsoft account that currently holds the active Microsoft 365 Family subscription.
Steps below:
Open Outlook then go to File > Office Account (or Account Settings).
Sign out of all Microsoft accounts.
Close Outlook completely.
Reopen Outlook and sign in only with the email that you want to retain.
Note: If you recently purchased additional space, please note that it may take 24 to 48 hours to update across all services.
