I appreciate what you've done so far, @mrtdg-ep. Could you please clarify what you mean by QuickBooks Self-Employed (QBSE) not accepting payments? This will allow me to provide a more accurate answer to your query.
On the other hand, if you're referring to payments not downloading in your QBSE, I suggest refreshing your accounts.
Here's how:
- Go to the Gear icon.
- Select Manage account.
- Click the Refresh all radio button multiple times to update your banks.

If the issue persists, I recommend reaching out to our Technical Support Team. They have the necessary tools to securely check your account setup via screen-sharing sessions and provide solutions quickly.
Here's how:
- In your QBSE account, click the Help icon.
- Select Contact Us.
- Enter the question or topic you need help with.
- Click Continue.
- Choose a way to connect with us:
- Start a chat with a support expert.
- Get a callback from the next available expert.
