First question ... is this a C-corporation that started in 2018?
If not, a 2019 NOL is carried back 5 years, so it would be carried to 2014.
Second question involves your phrase "to 2018 return". You aren't actually re-filing 2018, right? You are just preparing the Form 1045 in the 2019 software, right?
My take on this is that you CAN go back 5 years to absorb the full NOL but you don't HAVE to. In my case, the entire NOL can be absorbed in the 2018 return.
Also, I still don't have an answer on why Lines 10 - 15 on the Form 1045 do not print. Do you you have any clue on that issue?
My take on this is that you CAN go back 5 years to absorb the full NOL but you don't HAVE to.
No. You can't pick-and-choose when to apply it. It must be carried back 5 years.
As for your actual question, sorry, I'm a ProSeries user so I can't help you there.
1. It is not a C-Corp
2. No I am not refiling 2018, but the instructions said to go back to 2018 return and enter the NOL in screen 15
Another issue: when I do the step in 2 above, it creates a 6251 AMT amount; there was no AMT in the original return; it seems counter-intuitive to me that this should happen?
