Thanks @RaymondJayO  that helps.   You showed adding the second line for the detail of the bank fee to the check (and I do have an expense account already for bank fees).  

My additional question is though, do I likewise add an additional line when entering the invoice from the vendor too?   otherwise the invoice amount doesn't end up matching the check payment amount.

(Sorry to be such a beginner at this, but I recently took over as treasurer for an HOA...this isn't normally my field of expertise...)

thanks for any insight - David Soniat
