Thank you for posting in the Community, @ardythe.
You can access the reconciliation page after entering the ending balance on the Begin Reconciliation window. When you click Continue, this will take you back to the reconciliation page.
If you still can't view the Reconcile Now and Leave options, I'd recommend using the Verify/Rebuild tool to check if there are any company file errors.
For the outlined steps, please refer to this article link: Verify and Rebuild Data in QuickBooks Desktop.
Once your file is free of any errors, you can go back to the Reconciliation page again and check if the options are now visible.
Keep me posted if you have other questions or follow-ups. I'm here to help however I can. Take care and have a good one.
