How do you unlink a bank account linked for online payments. I need to remove it.

Hello, jennifer-peacefu. 

To unlink bank accounts we need to change the payments account in the Account and Settings menu. Please take note that the bank account you're going to use should be transnational. This means that there should not have limitations for QuickBooks to put money in and take fees out when needed.

Here's how to change your payments account:

1. Go to Settings ⚙, then select Account and Settings.
2. Navigate to the Payments tab and go to the Deposit section and select Change bank.
3. Click Add new bank account.
4. Enter the Account Number and Routing Number of the bank account and select Save.
5. Verify the bank information and then select Submit.
