I closed my bank account. Bank balance is zero, but QB online shows a negative $12 balance. My QB In QB balance is zero. How do I fix the bank balance?

Let's make sure to fix your bank balance, Sweilers.

Generally, there are several reasons why your bank balance differs from QuickBooks. This happens if there are expenses that have cleared the bank but haven't been entered into QuickBooks, and your bank balance is less than your QuickBooks balance.

However, if payments haven't been entered into your QuickBooks balance, your bank account balance is higher than your QuickBooks balance.

With this scenario, you'll want to make sure to review your account register or chart of accounts and compare them to your bank statement. Please take note that the QuickBooks balance will depend on the transactions that are being entered or those that have been categorized. Once you're able to locate the discrepancies, you can edit or update the transactions. To do so, follow the steps outlined below:

1. Go to the Gear icon, then select Chart of accounts.
2. Find and select the transaction in the account register to expand the view.
3. Make changes to the available fields.
4. If you want to change something in the grayed-out sections, select Edit. This opens the full transaction form where you can make additional changes.
   
5. When you're ready, select Save or Save and close.

The issue is with the bank not QB.  What happened is as follows:

I transferred all cash from my bank account to a new bank account leaving the bank balance at zero.  The bank charged a $12 service charge on the old bank account.  A QB download occurred relfecting a negative $12 bank balance.  I called the bank they closed the account and waived the service charge.  The bank disconnected the account from the download and I never got a updated from the bank reflecting a zero balance in the bank account.

How can I fix this?

I appreciate the additional information you have shared, sweilers5.

Since your bank has already closed your old account and waived the $12 service charge, we can exclude the downloaded fee from your records. By doing so, we can correct your balance and ensure that it reflects zero in QuickBooks Online (QBO), maintaining the accuracy of your financial data. 

To exclude the service charge in QBO on the web, here's how:

1. Go to Transactions, then select Bank transactions.
2. Select the tile for the account you want to review.
3. Go to the For Review tab.
4. Click the checkbox of the service charge to exclude.
5. Select Exclude.

Additionally, I'd recommend reconciling your new bank account regularly. This effectively tracks your income or expense transactions and identifies any potential errors. To assist you in performing and resolving reconciliations, refer to this article: Learn the reconcile workflow in QuickBooks.
