You're welcome, @GeorgeTheCat. It's our pleasure to help.
To guide you with submitting a self-attestation to Intuit for PCI compliance, I suggest reaching out to our Customer Support team. They're the ones who can guide you through the step-by-step process.
You can check their chat link or phone number by going to this article: Contact Payments or Point of Sale Support. Then, scroll down to the QuickBooks Payments section.
Here's more information about the QuickBooks Payment Card Industry Data Security Standard (PCI DSS) compliance.
Then, check out these IRS requirements for merchant processing when reporting payment card and third-party network transactions: Tax Compliance for Credit Card Accounts.
Let me know if you have further questions about the PCI compliance. I'm always here to assist. Have a wonderful day!
