I accidentally deposited a personal check into my business account. After I transfer the funds out, how do I account for it in QuickBooks online?

Hi there, @Cincygirl100.

You can use one of the default equity accounts to categorize your funds. Let's go ahead and discuss this process.

Creating a journal entry is the commonly used method to record transactions affecting your personal and business accounts. The concept is to use the Owner's Equity account as the detail type to use in recording these journal entries.

However, I'd still recommend contacting your accountant for guidance in choosing the account category of your journal entry. They can also share the best accounting practice to follow considering the needs of your business and accounting books.
