Let me guide you on how to reconcile an account, cashivali0509.
You'll have to make sure to review the opening balance if you're reconciling for the first time. After you have entered the balance, you can now start your reconciliation one at a time. Please follow the steps below for the correct process.
In QuickBooks Online, click the Gear ⚙ icon and then Reconcile. If you're reconciling for the very first time, select Get started to continue.
From the Account ▼ dropdown, select the account you want to reconcile. Make sure it's the same one on your statement.
Important: If you see a message about a previous reconciliation, select We can help you fix it. You need to fix this before you start.
Review the Beginning balance. Make sure the beginning balance in QuickBooks matches the one on your statement. Here's what to do if they don't match.
Enter the Ending balance and Ending date on your statement. Some banks call the ending balance a "new balance."
If you see it, review the Last statement ending date. This is the end date of your last reconciliation. Your current bank statement should start the day after.
When you're ready to start, select Start reconciling.
Also, QuickBooks automatically generates a reconciliation report after your reconciliation. You can view and print the report for your future file. Read this article for your reference: How do I view, print, or export a reconciliation report?
