Consecutive NOL years

I had a NOL in 2018. I used Form 536, worksheets 1 and 3 to calculate the carryover amount to 2019.  In 2019, I incurred another NOL (excluding the 2018 carryover NOL) and calculated the carryover amount to 2020 using same worksheets.  I thought we must use the earliest NOL first. Using the form 536 instructions/worksheets, all of the 2018 NOL carried over to 2019 will not be used at all.  Instead, the losses of 2019 will be applied toward non-business income and any leftover carryover to 2020.  So, the entire 2018 NOL is carried to 2020 and $0 is applied to 2019 income.  Is this right?
