On the other hand, you can create a journal entry to normalize your account balances and help fix the issue. I'd recommend consulting with your accountant so you'd be guided properly in choosing the right account when creating a journal entry.
Don't hesitate to leave a comment below if you have other questions about managing your bank transactions in QuickBooks. I'm always here to help.
