The Intuit Terms of Service state:

Instant Gratification.  If retroactive legislation is passed in March, we do not guarantee that customers will have updated software for all 43 states within a week, especially if even IRS can't figure out how it works for two weeks.  However, we will assume customers have average IQ and will be able to make adjustments to state returns with a few keystrokes.  If states do not update their software to accept such changes, we assume no responsibility.
