Thank you for your quick response. I received a K-1 for Interest Income on EE & I U.S. savings bonds after I filed my 2021 Fed and State returns. I then filed and paid additional taxes on amended returns (both Fed & State) for the K-1 Income. I didn't realize that Interest on U.S. savings bonds were exempt on State Income Tax returns. Should I file another amended to the State to request a refund?
