Hi there knshah91,
Thanks for reaching out about reconciling your accounts. QuickBooks Desktop is a great tool able to help you keep track of sales and expenses so you can see the profit of your company. I can point you in the right direction for assistance with reconciling.
In order to reconcile an account, you can follow the steps outlined in this article. You'll more than likely have to start where you left off, to make sure all transactions done after the last time you reconciled have been entered correctly so your account balances can be accurate. For further assistance with reconciling your account, I recommend reaching out to the QuickBooks Desktop support team outside of the Community. They'll be able to provide some assistance in making sure you can reconcile the accounts correctly. You can reach them using the methods outlined in the QuickBooks Desktop support policies.
If you have any other questions, feel free to reach out here.
