I am reconciling my business account but a deposit went into my personal account. How do I reconcile that?

Hi there, @scott97. 

Thank you for reaching out to the Community. It's my priority to help you sort this out. Sometimes things get missed, it's bound to happen every once in a while. 
 
To reconcile the transaction first, open the transaction and move it to the correct bank account. This way, it will appear in the right account. 

For future reference, you can check the reconciliation workflow to be guided in reconciling: Learn the reconcile workflow in QuickBooks. 

Upon sharing this, I still suggest consulting with your accountant. He/She might have specific instructions on how to handle the deposit. 

Stay in touch with me if there's anything else I can help you with. Just mention my name and I'll get back to you. Have a great day!
