Need to deduct the state taxes I paid last year. The label for where to enter this is, "Payments for 2015 or a prior year .." Why would this say 2015? Is that a typo?

I am filling out my 2017 taxes.  I need to deduct the state taxes I paid last year which was 2016 state taxes.  I know I need to go to Federal Taxes > Deductions and Credits > Estimates and Other Taxes Paid > Other Taxes Paid however the label for where I would enter the 2016 state taxes paid is actually labeled, "Payments for 2015 or a prior year state or local income taxes paid in 2017"  Why would this say 2015?  Is that a typo?  If not and that is the area to enter 2015 state taxes paid, where do you enter state taxes paid for 2016 state taxes?  Last year's state taxes.
