Sum Output per Year

With Power Query

let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(Source, {}, "Attribute", "Value"),
    #"Added Custom" = Table.AddColumn(#"Unpivoted Columns", "Quantity", each if Text.Contains([Attribute],"Quantity") then [Value] else null),
    #"Filled Up" = Table.FillUp(#"Added Custom",{"Quantity"}),
    #"Filtered Rows" = Table.SelectRows(#"Filled Up", each not Text.StartsWith([Attribute], "Quantity")),
    #"Changed Type" = Table.TransformColumnTypes(#"Filtered Rows",{{"Value", type date}}),
    #"Inserted Year" = Table.AddColumn(#"Changed Type", "Year", each Date.Year([Value]), Int64.Type),
    #"Grouped Rows" = Table.Group(#"Inserted Year", {"Year"}, {{"Total Quantity", each List.Sum([Quantity]), type number}})
in
    #"Grouped Rows"

Power Query is a free AddIn for Excel 2010 and 2013, and is built-in functionality from Excel 2016 onwards (where it is referred to as "Get & Transform Data").

It is a powerful yet simple way of getting, changing and using data from a broad variety of sources, creating steps which may be easily repeated and refreshed. I strongly recommend learning how to use Power Query - it's among the most powerful functionalities of Excel.
