Payment Method Hacked - PayPal Payflow Pro iFrame

I think my website was hacked, but I cannot find the incriminating code.

Opencart 2.3.0.2
PHP 7.1

When the Payment Method:
PayPal Payflow Pro iFrame
is enabled, there is a form for filling in credit card information on the Checkout page Step 5 Payment Method. This should not be there. A form for entering credit card info should not appear until Step 6 Confirm Order where it inserts an iFrame.
