This same thing has been driving me completely crazy. I ended up highlighting and ctrl+c (copy) the memo that incudes the payment ID. Then at the bottom, I click "More", "Delete" and delete the payment. Then I re-enter it as IPN (You could also enter as check if you want to), "Deposit to: [choose your account] and add the memo to the memo box. Save and Close. Then it shows up and I can reconcile my account. I literally hate QB online, but am stuck with it because of the nature of our billing process.
