Why is my reconciled number of deposit and amount too high

Let me share some possibilities as to why you have a high number of deposits and amounts in QuickBooks Online (QBO), Nunzio57.

Since you've mentioned that your beginning balance and statement ending balance match in your bank statement, I see that there might be transactions in your online banking that haven't matched with the transactions in QBO. Thus, ensure that you match it to the transactions created in QBO accordingly to avoid having overstated deposits in your reconciliation. 

It's also best to review and compare your transactions in bank statements or online banking and the transactions in QBO. You can consult with an accountant to ensure that your data is accurate. 

In addition, you can refer to this guide to learn more about what to do if QuickBooks Online doesn't match your bank statement: Fix issues at the end of a reconciliation in QuickBooks Online.
