I'll gladly share the solution needed when applying a Journal entry to a bill, kapp.

You can begin by deducting from the Accounts Payable account and crediting from a Bank or Expense account. I also suggest consulting with your accountant to ensure proper recording of what accounts to use. 

After that, create Pay bills to link it to your newly created journal entry. Doing this will reduce your total payables. Let me show you how to do it:

1. Click the + New button.
2. Select Pay bills.
3. Choose the bill you need to link to your journal entry.
4. Click Save and close.

I've attached screenshots for visual references:
