How do i enter a supplier return to my cheque account

I have Reckon Accounts Premier - Contractor Edition 2014. I purchased an item from a supplier via EFTPOS (selecting CHQ Account). I then entered it into Reckon via Write Cheques (no CHQ #). The item (not suitable) was subsequently returned to the supplier. How should this be entered into Reckon?

Why isn't there a 'Refund/Credit' button in 'Write Cheques' to make the process easy, as this is a common requirement??
