E: Add the WI - Credit for Net Tax Paid to Another State (Schedule OS) to your Wisconsin return.

If you have already added the Schedule OS to your WI return, and are still receiving a message telling you to add it, the most common cause is having a manual entry on your "WI - Income Tax Return" form, on the line labelled "Net income tax paid to another state. Enclose Schedule OS". Because this is an override field, it is preventing the data you're entering on the Schedule OS from being read properly by our system. Please return to your "WI - Income Tax Return" and remove the entries on this line (both the amount and the state), and save the form. This will allow you to proceed.
