When I select +New check. The default check number is one that was used just 2 days ago. How to get default check number to always automatically be a new check number?

I recognize the significance of maintaining accurate check numbers in QuickBooks Online (QBO), hooang. I'm here to help you to ensure they are sequentially organized within your account. 

When generating a new check, the number will automatically update for the next time a check is created. If it's displaying a number from the past, we can perform some troubleshooting steps to fix this. There are times when the browser is full of frequently accessed page resources, which causes some errors or unusual responses. 

Let's start accessing your account using a different or private browser. You can use either of these shortcut keys:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Shift + N

Once logged in, try to run payroll again. If it works, I recommend clearing your browser's cache. Doing so will remove the historical data and access QuickBooks with a clean slate. You can also switch to a different supported browser.

I've been having the same issue, so I will try these steps. But just this week, when I edit bill payments to correct the check number, the transaction shows saved in the pop up box, but the check number reverts back to the original. How can we correct the check numbers?

I understand the frustration you're experiencing with the check numbers reverting back to the original after editing bill payments in QuickBooks Online. It's definitely an inconvenience, but there are a few steps you can take to address this issue, @teegardin13. 

First, I recommend trying the troubleshooting steps mentioned earlier, such as clearing your browser's cache and cookies or using a different web browser to see if the issue is specific to the browser you are currently using. Sometimes, unusual behavior in web applications can be related to browser issues.

If the issue persists after trying these steps, I advise you to contact QuickBooks Online support directly. They can provide specific troubleshooting steps and investigate the issue further to help you resolve the issue with the check numbers not being corrected in your bill payments.
