If you don't know what type something is, you can hover the mouse over it, and VS will tell you.
In this case it's a IEnumerable<IGrouping<string, string>>
Which means that it's a collection of Groups of string key / string value pairs.
Each Group in the collection has two properties you are interested in: the Key (which is the barcode number) and the Count method which tells you how many items are in each group.
So it's pretty simple to access the barcode and count:
string[] lines = File.ReadAllLines(filePath);
var barcodes = lines.Select(line => {
    string[] parts = line.Split(',');
    return parts[2];
});
var x = barcodes.GroupBy(b => b);
foreach (var y in x)
    {
    Console.WriteLine($"{y.Key} : {y.Count()}");
    }
For your sample data you get:
1578456329781 : 1
1578453697235 : 3
1548795358155 : 1
