State Tax Refund Taxable (Married; Filing Jointly)

My wife and I just got married in 2018. She took the standard deduction in the 2017 tax return, while I benefitted from itemized deductions. For this years tax return (2018 tax year), we're filing jointly, I was wondering if only my state refund from 2017 is taxable (since I itemized my deductions) while my wife's state refund is not.

 

Thanks in advance for the help!
