1099-G for MN income tax refund

I received MN income tax refund recorded in 2019 Form 1099-G.

TT asks "What type of payment did you receive?" options: 1-taxable grant, 2-Agricultural...., 3-Market gain, 4-Reemployment..., 5-Business or farm tax refund

My 1099-G doesn't mention any of the above.

 

For income tax refund what option should I select?
