I've got the same issue as all of you. Tried everything to delete the entire form, as well as un check the box. Can't do either.
Too bad, as I would like to file my taxes as I have a refund coming.
Also, noted that when I had done the Fed taxes about 2 weeks ago, and even ran the "Smart Check", everything was fine. I thought it smart to hold off and wait a few weeks incase I got any revised documents, which I haven't. Something in the past few weeks which updated, apparently has a bug in it. Hope TT can resolve this soon.
