Once you enter the tuition slip information in the Student section, TurboTax will assign the proper amount of credits needed to lower your tax payable to zero. Input the full value of your tuition for 2017 and any unused amounts from previous years (if you haven't imported your 2016 information into your 2017 return or used auto-fill my return). Check the detailed tax summary for line 323. This reflects the amount of tuition claimed for you.
