If my unreimbursed employee expenses in the transportation industry exceed 2% of my AGI, why does my tax liability/refund not change?

[brandicesk]

Does the version of Turbotax I am using, affect the outcome?

[RichardG]

TurboTax starts with giving customers the standard deduction, and until the customer's total itemized deductions exceed the standard deduction, your refund or liability will not change.

The deduction for job-related expenses is one of the itemized deductions.  So even though you meet the 2% adjusted gross income threshold for this deduction, until that deduction plus your other deductions exceeds your standard deduction, your refund or liability stays the same.
