I can enter the negative balance but it will not reconcile. I just get a blank screen rather than the normal reconciliation screen. Now it is impossible to reconcile anything.
Let's get this sorted out and display the transactions in the Reconcile page, lbg3093.
Let's make sure the Hide transactions after the statement's end date option is not turned on in the Reconcile page. You can uncheck that option located on the top right of the screen to see the transactions for that period (if it is activated).
If not, it's possible there's a damaged data on the company file preventing the transactions to appear. You can follow the steps in this article to troubleshoot the issue: Resolve data damage with your QuickBooks Desktop company file.
Then, try accessing the Reconcile page again to see the transactions for Checks, Payments, Deposits and other Credits.
