I have been asking this same question for a month now and no one with TT seems to have an answer. TT simply will not populate this form at all. Even if you add the form, it won't help you populate it. This is a glitch TT missed and never did anything about it nor can they advise on it. They are so kind to send me the link to the IT-558 form, which any moron can find and google themselves, but that's not even what I was asking for. TT loves to answer questions that I am not even asking. I wanted help with the form. Whatever you do, don't do the "file as an amendment" as TT advises. TT says file as an amendment, even if you're not amending, and it will populate. Not true at all. You will just have to back and delete a bunch of crap to correct it. It was just a suggestion some TT bot put on here. Terrible advice. I figured out that I just needed to print out the IT-558 Form and place zeros in the columns that apply and total zero at the end. Hope this helps.
