You can file your individual income tax return electronically and then you must separately file Form 709 by mail.
As has been mentioned, TurboTax does not support Form 709. Further, Form 709 cannot be filed electronically (even by a professional tax preparer using professional tax preparation software); it must be printed and mailed.
