Do we enter Oregon College Savings Plan contributions made in 2018 before April 15, 2018 into the 2017 box?

Oregon allows you to apply these payments made prior to April 15, 2018 to your 2017 taxes but I'm not sure how to enter this in Turbotax.  Turbotax only includes a box for "Oregon 529 College Savings Network deposits made in 2017".  Do I enter these payments in this box even though they were made in 2018 or is there somewhere else they should be entered.
