Why doesn't Turbo Tax support MI Form 5081? I was just notified that I needed to file this form and now I owe a penalty and interest. I had no idea it was needed and trusted Turbo Tax to review and ensure that my taxes were complete. If Turbo Tax isn't going to support all forms, at least advise that unsupported forms are needed and refer us to the appropriate website to obtain the form and instructions. Other people have posted the same issue but Turbo Tax doesn't address the problem - just states that the form isn't supported. How are we supposed to know the form is needed? We put confidence in Turbo Tax and are left in the dark and have to pay penalties and interest. Very disappointed in Turbo Tax!
