do you really have a loss that can be carried back? other income and deductions must be taken into account
NOL Offset with Non-Farm Income
if you have other income which is equal to or greater than the current year’s Schedule F farm loss, then the farm loss is allowed in full and there is no NOL. Other income could include gains from the sale of breeding livestock, culled breeding livestock, other business assets or non-business assets. Other income could also include salary and wages from off-farm employment.
Turbotax does not calculate NOL. you would need to use form 1045 schedule A or
IRS PUB 536

Turbotax does have the NOL waiver statement.
