State Income tax refund not filed?

IRS has notified me of a reported state tax refund in my 2019 Form 1040. This is strange since I have filed using Turbo Tax from may years and this information is always (correctly) carried over. When I look at my 1040 however, there is no evidence that I can see of the state tax refund being reported. I can only see the refund showing up in a Federal Carryover Worksheet (as well as the State Carryover Worksheet), so the tax refund does indeed show up in some places. How can this be corrected?
