Married 2020 - Itemized and Standard deduction in 2019

I got married in 2020.  In 2019, I itemized and my spouse used the standard deduction.  I received a refund in 2020 for my 2019 state taxes.  How do you enter the information in turbotax?  I think my state refund should be taxable since I itemized.  Estimates Standard 12400, Itemized 14200, state refund 500.  I think my portion of the state tax refund is taxable?  My spouse also received a refund but used standard deduction.  Total State refund for both of us is 1300.  Is all 1300 taxable or just my portion?
