2018 program some column headings are 2016 and 2017. Example: taxes in the home office deduction. The year before it has a 2016 heading, for this year it's 2017.

I'm not sure what to put here.  The amounts I paid in real estate taxes between 2017 and 2018 are very different so I need to know if I should put the 2017 amount even though this is the 2018 program.  I also ran into this problem in the auto deduction section.  Im confused.
