Nice to have you in the Community, @ccasillas. I can provide clarification on reconciling.
As long as you have a bank statement that you can compare the transactions in QuickBooks with, you can reconcile the account. There's a resource that contains multiple articles to troubleshoot reconcile issues that I recommend: Reconcile Hub.
If I can be of any additional assistance, please don't hesitate to let me know. Have a good one.
