While the non-simplified way works, you run the risk that the IRS will (later?) get mad at you for changing methods.
TurboTax is definitely aware of the IRS change. When I talked to support last week (which I wrote up here, a few pages back in this thread), at one point Support Person 3 suggested something about a binary attachment to explain the wrong date (which matches with what @amankg mentioned here earlier in this thread). I asked him how do I do that, but he didn't know. It did seem like he was also checking with someone else, but we ended up not doing anything with this idea. Clearly, the binary attachment is something that TurboTax should be preparing - that document is from the IRS to tax preparation software companies.
That said, it sounds like they don't understand it... Hopefully that has changed since last week. I originally tried to file my taxes on Feb 27 (almost 3 weeks ago) - I hope they fix this soon.
