                    select new tutstat
                    {
                        btn_name = (string)query.Element("btn_name"),
                        strng = (string)query.Element("strng"),
                    }).ToList();

It sounds like it’s as simple as using Root.Element("Main_Screen") before the call to Descendants:

XDocument loadedData = XDocument.Load("HelpScreenData.xml");

var data = loadedData.Root
                     .Element("Main_Screen")
                     .Descendants("row") // Or .Elements("row")
                     .Select(x => new tutstat 
                             {
                                btn_name = (string) x.Element("btn_name"),
                                strng = (string) x.Element("strng"),
                             })
                     .ToList();

I’ve changed this from a query expression to a simple stack of method calls as the query expression was only adding noise.

You should also fix all your names to comply with .NET conventions and be more explanatory.
