Unable to reconcile bank statement to QB

Hi there, Karen8883. Thanks for sharing a good amount of details to help us understand what's happening in your reconciliation. 

There are a couple of reasons why there's a difference in the Reconciliation window. The first thing to check is if the opening balance in the reconciliation screen matches the opening balance from the bank statement for July.

If the opening balance is incorrect, the reconciliation difference persists even if the individual transactions match. Adjust the opening balance if needed to align with the bank. Mistyping the ending balance (e.g., entering $492.78 instead of something else) can cause also reconciliation errors. This can also apply to the transactions themselves, so make sure to review that everything has the same amounts.

However, you mentioned that you already made some troubleshooting steps on your end to sort out the difference. In this case, I'd recommend reaching out to our live support teams. They have additional tools, such as screen-sharing, to take a closer look at your reconciliation to pinpoint the cause of the issue.

When it comes to the transactions that are showing in both your main and credit card accounts, please note that QBO depends on the data that's provided by your financial institution. I'd suggest contacting your bank to check what's causing the issue.
