Thanks for reaching out to us, @Tiffiny Taylor Krugh.

I'm happy to provide some insight here. Invoice Payments in QuickBooks Online don't have classes. Rather, you'll need to assign the class to your deposit from the payment. I've included a screenshot below showing the class field on the Bank Deposit screen.

I recommend checking out Create and manage classes in QuickBooks Online if you'd like to master classes in QuickBooks Online.
