Thanks for the reply Thomas. I copied your response I received from you in an email notification in response to my question below. That was the answer looking for.
The reason I need to care of about how much 2018 NOL was applied to 2019 tax filing is because in 2020, I will need to include a statement describing how much NOL was carried forward from which tax year.
This would be correct. The business losses in the current period would be netted against non-business income to determine the current year net operating loss (NOL.) Only after you did that would the NOL from the previous year be applied to the current year. Since the current year has no net income, the NOL from the previous year would then be applied to the next year.
