There's a fair bit of sleaze when you use TurboTax, at least this year:

* If you enter any IRA contributions, including Roth IRA, it suggests you update to Deluxe to get "your biggest refund" even though Roth IRA contributions don't qualify you for deductions.

* They plaster "e-filing your federal returns is free!" everywhere while obscuring the fact that they want $20 to help you e-file a state return

* The audit stuff you mentioned

* They no longer include one free state as they have in previous years, but this fact is not mentioned anywhere in the product description
