Not true about being required to upgrade to Premier. I have premier and get the same error. I'm manually sending in the amendment form (1040-x) so I don't get a letter from the IRS. TT chooses to print a negative sign (-) instead of the IRS instructed parenthesis () on the printed forms. I had to go in with a PDF editor to modify all the negative entries. At least the proceeds and basis now line up with the 1099-B. Such a terrible experience for only a few lines of negative options proceeds.
