Hi there, Eugene. I'm here to help you fix your beginning balance so you can proceed with reconciling your account.
Yes, aside from updating the opening balance through the account's register or chart of accounts, you can also use a journal entry (JE) to correct the balance. JE needs an accurate recording especially on the accounts under the Credit and Debit section. Thus, I recommend seeking assistance from your accountant before doing the process. He or she can review your statements and use the accurate posting accounts to fix your account's beginning balance.
Once everything is corrected, you're now ready to proceed with your reconciliation.
Just in case you need help with fixing your completed reconciliations, you can also use this article as your guide: Learn the reconcile workflow in QuickBooks.
