Thanks for posting to the Community, @kenny-goh-finque.

I can share some information and directions about the beginning balance you see while doing bank reconciliation.

Normally, the beginning balance is the ending balance of your previous account reconciliation. If you're seeing this by mistake, you can compare your account statement and the ones in your bank register.

Once reviewed, you can uncheck the uncleared or pending transactions. These could be checks that are still uncashed or a customer payment that was already recorded in the system even if it’s not cleared in the bank. This way, it won't be included when you reconcile your account.

I'm adding this article for more detailed information in managing your income and expense transactions:

Additionally, I recommend consulting your accountant to guide you accurately in performing the reconciliation process.

Please comment if you have other questions about reconciling your account in QuickBooks. Anytime I can help. Keep well!
