Bank history registry is no longer available how do I retrieve it again?

Hello, @bcconstruction-a.

Welcome to the QuickBooks Community. Allow me to help retrieve your bank history.

First, ensure that you filter transactions correctly when finding it and sort the of transactions by date,reference number, payee, or reconcile status.

Here's how:
 

1. Move over any column header. If a Sort icon (▲ or ▼) appears, you can sort the transactions by the value in that column.
2. CHoose any sortable column header to sort the account history by that value by ascending or descending order.
    

Note: If you sort by any column other than the Date or Reconciliation status, the Balance column displays n/a.
