Deductions & credits

TurboTax Deluxe online does have a place for a net operating loss carryforward.

To enter your 2021 NOL carryforward:
 

1. Type net operating loss in Search
2. Select Jump to net operating loss

As Champs @Anonymous_ and @Mike9241 say, TurboTax does not calculate a NOL carryforward, so you will have to use Schedule A of Form 1045 to figure your carryforward each year.
