Since you appear to be using TurboTax Online, you can't readily view your return-in-progress as readily as if you were using the desktop edition.  See the TurboTax Help article How do I preview my TurboTax Online return before filing? for guidance in viewing your return before filing.  If you've entered information that would appear on a West Virginia Schedule M, the schedule will be present.
