No. The new tax laws don't kick in until 2018 and won't affect  you until you file your 2018 tax return next year.

If this is true why are my deductions that I have written off in previous years not making a difference?

The TurboTax program starts off giving everyone the standard deduction.   Once you enter all of your various types of deductions (medical, taxes, interest, donations, employee job expenses subject to the 2% rule, etc.),  and if that total is higher than your standard deduction, then TurboTax will switch over to itemizing deductions, which will appear on Schedule A.   TurboTax will also determine if your medical expenses exceed the 7.5% floor and start to count.

Are your job expenses as an employee (i.e., are you paid W-2 wages)?   If so, the employee job expenses fall under the 2% rule.  That means that employee job expenses will not start to count until they exceed 2% of your AGI, and only then if you have  enough of the other types of deductions to itemize on Schedule A.

So have you entered all your other deductions--medical, taxes, interest, donations, and the employee job expenses, etc.?     Does that total exceed your standard deduction?   And does the total of your employee job expenses exceed 2% of your AGI?
