We appreciate you for dropping by this thread, FL_Guru.  It appears that the Add a Change Order window is not displaying in QuickBooks Desktop Enterprise 24.0 (QBDT) after you add lines to an estimate and click Save and Close.

This functionality could be related to your current software which is QuickBooks Desktop Enterprise and the video snip shared is for QuickBooks Desktop Enterprise Accountant Edition. This is why the Add a Change order window doesn't appear with your current QuickBooks product.
