How can I delete pending transactions that I cannot select?

I asked the QB agent for help but he couldn't even see them on his system.

I appreciate the screenshot you've shared, @davepearson.

Since deleting pending transactions needs to be done through our support team, I suggest contacting them again. I understand that you already contacted them before, but they're the right support group who can help delete your pending transactions.

To reach them, please follow the steps below:

1. From your QBSE homepage, click QB Assistant at the top.
2. Type in the chatbox contact support. 
3. You'll now be provided options on how would you like to connect to them.
4. Choose the Get a callback or Start a message option to talk with a live agent. 

Please refer to this article for the different types of support we offer at Intuit and its availability: Support hours and types.

Keep in touch if you need any more assistance with this, or there's something else I can do for you. I've got your back. Have a good day.
