rdbreazile: Form 1040-X (amended return) won't be available through TurboTax until mid-February. I'd probably give it a couple of weeks past that (say end of February or first of March, but still way ahead of filing deadline) before submitting your amended return. Remember, you must mail your amended return. By the way, I'd also suggest mailing your return via certified mail so that you have a record of when the IRS received the return (just to cover yourself).
