Starting this year, the Audit Risk Meter is only available in the
desktop products Deluxe and higher. It is no longer a feature of the online
products. We've been telling TurboTax that a lot of online users miss
it, so maybe they'll consider putting it back next year.
By the way, you can download a prior-year *.tax data file from your Online account and transfer it into a current year desktop return (CD/download). So if you do move from the Online version to the desktop version in the future, you can still transfer in the prior-year data.
