Has anyone heard of some deal where you can get your taxes done for free if you made less than 30K?

I live in Chicago and I remember seeing an ad at a bus shelter about two weeks ago stating that if you made less than $30,000 in the last year, you could get your taxes done for free. Does anyone know what this is all about and possibly the URL? I recall the ad had a URL on it, but I haven't seen the ad since.
Update: The ad I saw looked like it was some state-sponsored program, not TurboTax. I can do my own taxes anyway, but I thought I would check.
