If the amount in the total Itemized or Standard deduction was $12,200 if you were singe, $18,350 for Head of Household or $24,400 for Married filing jointly, it means you took the Standard deduction and you don't need to include the state refund to your income in 2020. If there is a different amount, then you itemized your deduction last year and need to include that amount as income this year.
