Thanks for you quick response. I had determined it was in the form K1 as I was in the K1 section when I received the message in my post above. My question, more specifically is - the Other Situations section (in the K1 section) says: "I have At-Risk losses carrying over from 2017". When I select that option, it takes me to the At-Risk Limitation Allocation Worksheet. Do I enter my At-Risk amount here? And, if so, which line? OR, do I not select the "I have At-Risk losses carrying over from 2017" because when I don't select it, it takes me to the option to choose Simplified or Detailed method for entering the At-Risk amount.
