Get your taxes done using TurboTax

Yes, I have an amount of $348 in box 2 and $104 in boxes 7a and 10. So I am assuming federal tax has already been withheld for the income and I'll report it as below. The two questions I have are:

  1. Why can't I report this as I usually report dividends in a 1099-DIV form (since the income code in 1042-S is 06)?
  2. Can I eFile using TurboTax with the caveat being that I can't attach my 1042-S along with my return?
