State tax filing

TT is assessing an underpayment penalty for the state of CA even though I meet the third bullet point. Specifically my withholding is greater than 110% of the CA tax show in my 2018 return. Form 5805 is being populated but Part-II/Line-5 is blank when it seems like it should have my 2018 total CA tax value. I used TT for my 2018 tax preparation and for 2019 imported values from 2018. What could cause Form-5805/Part-II/Line-5 to be blank ? and how can I fix it so that TT considers this condition ?  Thanks-
