Hi PacificInterlude,

I appreciate you for posting your concern on this thread.

Since you're still unable to see the American Express account you're trying to link, I'd suggest sending a request to your bank. Let me guide you with these steps:

1. From the Gear icon, select Connect bank.
2. Enter American Express Business Checking.
3. Click Show more until you see Still can't find your bank?
4. Enter your bank's URL.
5. Click Request.

In the meantime, you can add the transactions manually. I've added this reference as your guide:  Manually add transactions in QuickBooks Self-Employed.

You can always post again if you have concerns. Keep safe!
