How to remove outstanding transaction from account reconciliation

I (foolishly) adjusted a payables invoice several months after I'd reconciled the Credit Card account from which I paid the invoice.I did this as part of my year end review of my books (year-end is Sept 30). (The adjustment was to move the expense to another account.) I suspect that I should have done it via an Adjusting Journal Entry rather than adjusting the invoice.
That item is now showing on my Credit Card account reconciliation list as outstanding. I realize that Simplay Accounting is showing it correctly from its perspective, but only because it's being fed information by a person whose knowledge of accounting is quite basic.
A possible complication is that my year end is now complete.

Is there a way that I can remove this item from my outstanding transaction list?
