Why is the reconciled bank balance so much higher than the QuickBooks balance on the dashboard?

Good to see your post here, schuitmngwg.

Let me answer why there's a difference on balance between reconciled bank and QuickBooks balances.

The QuickBooks balance is the total balance of all bank transactions that you’ve added or matched to QuickBooks. While the bank balance is your bank's actual balance from the last bank feed update. When the bank balance is higher than your QuickBooks balance, there's a possibility that some bank transactions are causing the difference. 

Below are the list of possible reasons why these balances don’t match:

• Outstanding transactions.
• New transactions for a connected account.
• Duplicate transactions.
• Edited or deleted transactions.
• Card (liability) account.

Depending on the factor that’s mentioned above, there are different steps to fix your issue. Here’s an article on the steps to fix or adjust these factors: How to Fix Differences Between QuickBooks Balance and Bank Balance.
