Deductions & credits

Ok, so NOL and QBL are totally unrelated, so therefore whatever I may do with my  2018 NOL, my 2018 QBL is still carried forward to 2019 in figuring 2019 QBI, therefore Turbo Tax is correct in carrying forward the QBL amount of ($8454) to line 3? And it will continue to be carried forward until used up against enough positive QBI?
