I've got you covered, flyalaskamom.
Since the credit card charge is still showing as pending from your customer's credit card company, I'd recommend getting in touch with our Payments Support Team. This way, we'll be able to pull up your merchant account in a secure environment and check if they can still cancel the credit card charge.
You can connect with us through this link: Contact Payments Support. I also encourage checking out our support hours first to ensure that we address your concerns on time.
If you need track when QuickBooks deposits customer payments into your bank account, you can check the deposit speed for your product.
I'll be right here to continue helping if you have any other concerns or follow-up questions. Just tag my name in your posts and comments.
