How should I enter information about the changes on my amended Wisconsin return?

You don't need to enter each line separately if they were the result of the same change. You can just list the first line where an amount was changed.

Example 1
You amended your return to include an Angel Investment Credit passed-through to you on a Wisconsin Schedule 3K-1.

Changed form or schedule and line number:
Schedule VC, Line 3a
Details of change:
I received a Schedule 3K-1 after I filed that showed passed-through Angel Investment Credit. I entered this on Schedule VC. That amount also carried to other forms and schedules.

Example 2
You're amending your return because the amount entered for state tax withholding on your Form W-2 was incorrect on your original return.

Changed form or schedule and line number:
Form 1, Line 25
Details of change:
The tax withheld on my W-2 was $3,124 on my original return. It was corrected to $3,214.
