Thanks for getting back to the QuickBooks Community, @PI1417. 

I'm here to guide you to the right support so you can get the help you need. 

Since the deposit record is from merchant service, that's the reason why the Received from option in QuickBooks is grayed out. I encourage you to contact our Merchant Service Support Team they have the tools to pull up your account and record the payment to the correct customer. 

You can contact our merchant support through this link: QuickBooks Payments. 

Please know that you're always welcome to post again if you have any other questions about the QuickBooks. Wishing you and your business continued success.
