Why am I all of a sudden getting an error message that says either my bank account or the parent bank account is incorrect and I need t check my chart of accounts.

Welcome to the Community space, @Skyball13.

I'm here to provide information on the issue you're encountering with your bank account in QuickBooks Online (QBO) 

 There are times when the browser you're using has data issues, thus causing QuickBooks to act weirdly. To verify, log in to your QuickBooks Online (QBO) account using a private browser. To do so, press this shortcut key on your keyboard:

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

If this works, you need to clear the browser's cache so the system can start fresh. If you get the same result while using a private browser, I suggest switching to a different supported browser.

In the case where you're trying to submit payroll, we've received similar reports. Therefore, I recommend reaching out to our Phone support team. They can add you to our notification list and you'll be informed via email once the update is available.

Moreover, I'm adding this article for the complete guide to creating payroll to pay your employees: How do I create a paycheck for an employee?

Return to this post if you have other questions about your bank accounts and other payroll-related concerns in QBO. I am here to lend a hand.
