I had to pay back more unemployment than I received for 2016, how do I enter this?

Because of a change in the way seasonal road construction workers can claim unemployment benefits, I had to pay back all of what I received for the first part of 2016 and part of what I received for 2015 (Total compensation for 2016 was $2,501., the total amount paid back was $3,674).  I'm unsure of how to enter this in TurboTax since it was for 2015 & 2016.
