why is my personal unattached accounts reflecting on my business acct in QB?

Welcome to the Community and thank you for coming here. I'm happy to help with your concern, @123311.

Before we start, can you clarify what accounts you're referring? Are they your QuickBooks Online or bank accounts? Do you mind sharing some screenshots? I want to ensure that I'll provide the correct steps to resolve your issue.

I look forward to hearing back from you and troubleshooting further!
