Yes, If you took the standard deduction in 2018 your refund should not be taxable in 2019.
After you enter your refund in TurboTax you will see a 'State and Local Tax Refund Summary' screen. Select 'Done'.
You will then see a screen titled 'Let's See if Your 2018 State Refund Is Taxable'. Select 'I took the standard deduction in 2018'.
You should then see a screen that says; 'Good News! Your 2018 State Refund Is Not Taxable'.
