Sage 50 Canada

I am trying to post a J/E to my A/P account but it doesn't show in the account search. I realize this means the A/P account is linked somewhere and I can't figure out how to unlink it. I think it is defaulted to Vendors & Purchases module.

I use Ceridian as our payroll provider and am wondering what is the best way to enter employer and employee deductions in sage when entering in the payment to the payroll provider?
