I appreciate the detailed information and thank you for reaching out to us here on the Community page, @kshinson.
The process you've followed was correct. If the period you're reconciling is for December 01, 2019 to December 31, 2019, then make sure that only those transactions within these dates are selected under the Reconcile page to avoid any difference or issues. There may be some transactions that were selected outside the period of reconciliation that affect the huge difference.

Post again if you have any other QuickBooks or banking questions. I'm a few clicks away to help. Have a great day!
