Thank you for visiting the QuickBooks Community, Krae6ixmadeit. I understand how vital it is to determine why $8500 has been withdrawn from your account. Let me route you to the right support to assist you further on this matter.

If you're using QuickBooks Checking as your bank, I suggest contacting our Merchants Services Support Team. This team is the best resource for such inquiries, as they're able to request account information. They can

verify where the money goes through and investigate why it took to your account.

If you're not utilizing the said bank above, I recommend reaching out directly to your financial institution to trace the money.

Lastly, I'm adding this article if you need steps on how you can see QuickBooks Payments statements: Common questions about payments deposits in QuickBooks Online. 

Don't hesitate to add a comment below if you have additional questions about this concern. I'll be right here to help, Krae6ixmadeit. Have a great day!
