Glad to have you here, @csoffice.

I’d be glad to provide you with details on how you can enter and pay bills in QuickBooks Desktop.

When paying a bill, it should be done via the Pay Bill option. If you write a check to pay a bill, there’s a possibility the bill will remain as unpaid. 

To link the check to your bill, here’s how:

1. Open the written check.
2. Go to the Expense tab.
3. Change the account associated to the check to Accounts Payable.
4. In the Customer: Job column, select the name of the vendor or agency where you paid the Property Tax bill.
5. Click Save and Close.

Once you save the check, you can now create the bill. Now, let’s pay the bill by applying the written check.

Here’s how:

1. Go to Vendors. 
2. Choose Pay Bills.
3. Select the bill you want the payments to be applied to.
4. Click Set Credits.
5. Go to Credits tab.
6. Put a check mark on the check.
7. Hit Done.
8. Click on Pay Selected Bills.

That should do it! This will allow you to enter and pay your bill using the check created in QuickBooks.
