Hello @faridanurani,
Welcome to the Community. I'm here to assist with your beginning balance so that you can reconcile.
When reconciling, it's important that you have an accurate beginning balance or the totals will not match. The following article contains additional information about correcting an opening balance, such as how to manually adjust it: My Reconcile Opening Balance Is Wrong. How Do I Make It Match My Statement?.
Additionally, @Anonymous has a post in the Community that goes over reconciling that I recommend looking at since this is your first time doing so in QuickBooks Online. You can access it at the following link: How to Reconcile an Account in QuickBooks Online.
I'm sure that you'll be reconciling like a pro in no time.
Of course, I'm only a post away if you should have any questions. Have a safe and fun weekend.
