Need to write and balance correctly

Potassium hydroxide and Hydrogen nitrate react to form Potassium nitrate, Nitrogen monoxide, Iodine, and water.

Ive worked on this for 3 days now, to no avail! I write it, but can't seem to balance it correctly!

Where does the iodine come from? You have too many products.
KOH +HNO3 = KNO3 + HOH.
