That is for a State tax refund that you got in 2018 from the State 2017 return.
If you itemized in 2017 on the Federal return it is income in 2018.
To enter this in TurboTax (and TurboTax will help determine if this is taxable income or not, so don't worry)
Go to:
Federal Taxes
Wages and Income
I'll chose what i work on
scroll down to Other Common Income and the first one, State refunds is where this goes.
