Welcome to the Community, krucki!

Let's edit your journal entry so you can link it to your bill.

You'll need to change the account under Debits into Accounts Payable and choose the name of the vendor. This way, you can see the journal entry on the Bill Payment page.

Here's how:
   1. Find the journal entry you've created.
   2. On the first row under Account column, choose the account you used to pay the bill and enter the amount under the Credits column.
   3. On the second row, choose Account payable and enter the amount under the Debits column. Then, choose the vendor's name on the far right under the Name column.
   4. Click Save and close.

Once done, you can link it to your bill by clicking add at the right panel part of the bill. Please feel free to see the screenshots below to see exactly what I mean.

If you have any other concerns, feel free to leave a comment below. Have a good day!
