Hi, @B2G Homecare. I'm here to help resend a check payment in QuickBooks Online (QBO) through QuickBooks Bill Pay. 

Since the bill payment has been processed but hasn't been deposited to your vendor's bank account, you can contact our Payments Support for a void check request. Then, schedule a new bill payment. I'll lay out the process below to accomplish this.

It's best to contact your vendor firsthand and inform them that you will be voiding the check. 

You can then contact our Payments Support team for the voiding process. Rest assured that they can also guide you on what steps to take next after the voiding process. Here's how to contact them:

1. Sign in to your QBO account.
2. Select Help (?) at the top right.
3. Select or type Contact Us.
4. Enter your concern, then select Let's talk.
5. Choose a way to connect with us:
   • Start a chat with a support expert.

Once done, you can schedule a new bill payment. 

For future reference, let me add this article about managing your expenses in QBO: Enter and manage expenses in QuickBooks Online. 

Keep us posted if you have any updates regarding resending check payments through QuickBooks Bill Pay in QBO. We'll do our best to assist.

I noticed you are the second person to post in this community reporting the same issue over the last 2 weeks. If the problem occurs repeatedly and you can't avoid paying your vendors by check, you should consider using another bill payment app. You can easily void a check in the dashboard and issue a new one without contacting any support team.
