I'm here to ensure you can transfer the deposit to your personal account in QuickBooks Online (QBO).
Since the personal account is not connected to QBO, I'd suggest depositing the amount to the Owner's Equity. But before doing that, let's delete first the wrong deposit. Simply go to your business account, then delete the transaction.
After deleting, please follow the steps below.
Go to the New icon, then choose Bank Deposit.
Choose the customer's name in the Received from the drop-down.
In the Account box, select Owner's Equity. If you don't have it yet, click the +New.
Complete the Payment method, amount, etc.
Hit Save and close.
Then right after, create an Expense transaction to return the money to your personal account.
Choose the + icon, then select Expense.
Pick the Payee name in the drop-down.
Complete the Payment account, method, and date.
In Category, choose Owner's Equity.
Enter an amount.
Tap Save and close.
Also, you can always run the quick reports by clicking the drop-down arrow beside View Register. This way, you can review your data, then customize it to show the specific details. See the sample screenshot for your guidance.
Additionally, I've added articles about the How do I question in QBO: Help Article.
