Hi Smiley,
QuickBooks is for recording purposes only when it comes to withdrawing equity funds.
In reality, you can send funds from your business account to your personal account. Then, in QBO, you can record it as a check transaction and use the equity account if you want to categorize it that way.
Please check out the steps in this article: Record paying back an investment.
If you have other questions in mind, please don't hesitate to go back to this thread.
