I understand how challenging it can be to encounter a message prompting you to add your QuickBooks Checking account when it's already added. Let's work together to resolve this and get rid of this message, dads.

Before proceeding, can I ask for a screenshot of where the prompt exactly appears? Adding additional details will help us provide accurate steps to fix this.

In the meantime, 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.
