Hey there, fitzgeraldsautos.
Thanks for reaching out to the Community for support. Only an accountant can unreconcile the account. Having an accountant can be beneficial for you and your business. You can add your accountant to your books by following the steps listed here. If you don't have an accountant, you can find one who has experience using QuickBooks near you by clicking here. In addition, here's an article on how to fix issues at the end of a reconciliation.
