This problem with Form 2210 for MAC users should be a high priorty for TurboTax and they are treated it like it is not really a problem. A simple program change should not take 2 weeks to complete. The idea that you would have to mail in your return after you purchase their product and spend the money is not acceptable. I guess they do not care since they already have our money. Unacceptable!!! Please voice your disgust too.
