If we are filing a SAR for a fraudulent check (drawn on our customer's account) that we did not cash, would I still mark Paying location under the Branch's role in the transaction? Or because we refused to cash the check, would I leave that question (#64) blank? Along the same lines for #25 the suspect's role in suspicious activity would I mark Payee/Receiver or leave blank? Thanks.

If the transactions were not negotiated at my Bank I would not check those boxes.
