Get your taxes done using TurboTax

how many of your transactions have 'adjustments' for wash sales, AMD or non-covered securities.  If that's not many you can input those as "one by one" with the details which will generate a form 8949, put in the rest at summary level, it will all get consolidated on Schedule D and you shouldn't need to mail anything.  I suspect you're doing a lot of trading which may be generating wash sales so this may not help you but wanted to let you know if not aware.
