Accidentally reversed receipt for NSF cheque

Hi There,

A customer had some bank issues which caused many of his payments to be returned.  He advised me of this in advance, but I had already processed and deposited his payment, which covered several invoices.  He came in to rectify the situation once he had straightened things out with his bank by writing another cheque.

Because I had already cleared the invoices with his original cheque, I reversed the original receipt (which I now realize that I should not have) and processed a new receipt with the new cheque.  Now I am not sure how to correct my mistake so that it does not affect my reconciliation.  I don't believe that a general journal entry will show up on my rec. statement screen.

Any advise?
