Hello there, @PrismEd.

Let me help share some insights about the bill transaction in QuickBooks Desktop.

Once you void a bill payment check, it will cause the bill paid to return to unpaid status. You can process another payment to marked the bill as paid. 

However, if the amount for the initial bill was withdrawn and deposited back to your account, you'll need to record a bank deposit in QuickBooks. Once done, create another bill and record the payment to mark it as closed. 

To record a bank deposit, here's how: 

1. At the top menu bar, select Reports.
2. Select Make Deposit.
3. On the Received From drop-down arrow, select your vendor's name.
4. On the From Account drop-down arrow, select Accounts Payable account.
5. Enter the Amount deposited to your account.
6. Select Save & Close. 

If you need further assistance with the steps, I recommend to contact our QuickBooks Desktop Support Team. They have additional tools to pull up your account and do a remote session. 

Here's how to contact our customer support:

1. Select QuickBooks Desktop Help from the Help menu.
2. You can also press F1 on your keyboard to bring up the same Help Panel. 
3. In order to route you to the correct support expert, we need to know what type of question you have.
