I apologize that I am just now seeing this post or I would have responded sooner. Your best option is not to try and fill out the form on TT. Just download IT-558 Form and manually fill it out and send it in to NY. If you try and amend through TT, it is way too confusing and in all actuality, you aren't really amending your taxes. You are simply sending in a missing for that NY is asking for. I hope this makes sense.
