Why is my "account balance" section saying I have much more money than I actually do?

Welcome to the Community, @handyman11_2.

I'll help you correct the opening balance of your account.

If you connect your bank and credit card accounts, the program will automatically download all of your previous transactions up to a specific date. Totals them after that and enters the date and opening balance for you. If there are discrepancies, you can correct them.

You can open your bank register and make the necessary adjustments to match your bank statement and your opening balance in QuickBooks.

I'll demonstrate how:

1. Select the Accounting from the top menu bar.
2. Go to Chart of Accounts.
3. Locate the account holding the transaction, then go to the Action column and click View register.
4. Find the opening balance entry. This transaction is likely at the bottom or end of the list if you've got the Date column sorted from newest to oldest,
5. Click the opening balance entry to expand the view.
6. Edit the amount. If you're not able to edit the amount directly on this screen, you can click the Edit button.
7. Click Save, then choose Yes to confirm the changes.

For future reference, you can refer to this article when you reconcile your account: Reconcile an account in QuickBooks Online.
