If I close my account, so I can restart from scratch, what happens to my QuickBooks Checking account?

Hi there, katie. Let's go over some details to help you in managing your QuickBooks Checking account.

When you sign up for QuickBooks Payments and QuickBooks Checking via QuickBooks Online (QBO), your Payments account is automatically linked to your QBO account. 

If you want to start a new QBO account, you can still use and connect your existing QuickBooks Payments and QB Checking account.

Here's how:

1. Go to Gear ⚙ icon, then Account and Settings.
2. Select Payments tab.
3. In the Existing account section, select Connect or Link Merchant Service.
4. Pick the QuickBooks Payment account you want to connect to. Then hit Connect.
5. Review the account info and make sure it's accurate. If everything looks good, select Connect.
6. When the connection is finished, sign out and sign back into QuickBooks Online.

I've added this article for more information: Connect your QuickBooks Payments account to QuickBooks Online.
