Yes you can still file your return jointly.TurboTax does not support Form 1042-S,you will need to enter all of the other forms and W-2s and e-file your tax return.
The good news is that you
don't need to file From 1042-S with your tax return.Instead, download Form 1042-S from the IRS website, print it out, and then complete and mail it according to the1042-S instructions.
