Let me know how it turns out – if you don’t mind.
I am tempted to file the federal return via turbotax (w/o the pre-pay stub) and then print out the WI return , make the change and mail it in.
Thanks for your help.

Did you add any additional documentation with the federal return, since the amount on your W-2 won’t match line 5a on the Schedule A?
I might file my federal return electronically and then file the WI return by hand.

Did you file your 2011 taxes yet and how did it work out?
I pre-paid my 2012 WI taxes and also hope to deduct these prepaid estimated state income taxes on my federal return.
2 questions:
– The 2011 IRS tax guide (p150) makes it sound that I cannot deduct these, since there is no reasonable basis to believe that I have this additional liability. Of course the IRS guide is not WI specific.
– How to you actually file this. I am using Turbotax (online) and there doesn’t seem to be a place for it.
It also automatically adds it to the State return and sure enough it shows up as an overpayment.
