Is it possible to amend a Wisconsin State tax return for a Schedule SB subtraction that wasn't initially taken? (The U.S. Armed Forces Active Duty Pay subtraction in this case).
On the Schedule AR - Explanation of Amended Return - which box should be checked?
What should be entered here "Indicate the line reference(s) from the form or schedule for which you are reporting a change and explain in detail the reason for the change."?
