You can deduct the Turbo Tax cost or any tax preparation fees you actually paid in 2016 on your tax return no matter what year it is for.   But  it is a Misc Deduction and only the amount OVER 2% of your AGI is deductible so it might not be worth putting it in at all.  And then all your deductions have to be more than the Standard Deduction to give you any benefit.  You can only deduct the actual fees not the extra Refund Processing Service charge you paid to have the fees deducted from your federal refund.

For example, you make $20,000 AGI.  Only the amount over $400 (20,000 x .02) would even be deductible.  And that's only for 20,000 AGI.  For like 50,000 AGI only the amount over $1,000 would be deductible.
