I'm enjoying the same issue.  A client disputed their payment, QB took the money back, I followed the instructions and created a dummy invoice for the original payment, and the "needs attention" message remains.  I text-chatted with a QB expert who told me she couldn't help (even though she introduced herself as a QB Online expert), and that I needed to communicate with somebody in QB Payments.  I then arranged for a callback that was cut short because of a bad connection.  They didn't try to re-establish the call.
