how to amend 2018 return to claim tuition and fees deduction using turbo tax premier

Does anyone know how to amend 2018 return to claim tuition and fees deduction using turbo tax premier ?

 

I installed "w_turbotax_1040_prm_amd_2018.120.0100" & intend to amend my 2018 return for the tuition and fees deduction that was extended by Congress in Dec. 2019. Somehow this version of  turbotax says "tuition and fees deduction is unavailable" still.  Please help if you can, Appreciate it.
