That change was so recent, that it may take several months for the tax software to be updated....but only IF...if TTX agrees to do so. Then you will eventually need the Desktop software to do the amendment.
1) First....the OR DOR has to decide HOW to implement it in their own computer system...2-3 months for that.
2) THEN the OR DOR has to interface with the computer software companies, outlining how it is to be done. a month or two for that.
3) Then the computer software companies implement the proper computer software capabilities....another month or two.
