Deductions & credits

This loss from my 2019 return was not a capital loss but rather a large loss due to expenses realized in discontinued businesses.  It should be considered a NOL and either carried back 5 years or ahead until exhausted.  From my research, it needs to be dealt with via a Form1045 or an amended return 1040X. Due to the size of the loss report on my 2019 return, I would never completely realize the benefit with a capital loss limit of $3,000/year.  I was looking for help on how to calculate the NOL in my 2020 return and for following years.  The EA at Turbotax seemed ignorant of this issue.
