In my opinion, TurboTax does it wrong. While it does not need the business name or EIN, it should have both of your Social Security Numbers on it.
But I agree with Tagteam that the IRS probably won't really care as long as both names are on it.
If only one person wants to make the election, I edit it so it only has one name on it and their SSN number.
To explain why I think TurboTax is wrong: The Regulation says that for a consolidated corporate return (one "parent" tax return that covers several "member" corporations), the election needs to state the name AND identification number of each "member" corporation. To me, that means you can't only use the 'first' Social Security Number on your Joint tax return - It should have the Social Security Number of all 'members' of the tax return.
