Deductions & credits

New information - now I just need to know how to enter this is TurboTax!
Directly from the Wisconsin Department of Revenue:

"Since you are allowed to deduct losses for your federal return but not for the state return, there would be a difference in the reported federal adjusted income. To account for this difference, you would need to create a "Wisconsin Only" form 1040 Schedule 1. Report only the winnings on line 8 of the 1040 Schedule 1. The totals of the 1040 Schedule 1 will then flow to line 8 of the 1040. This will create a new federal adjusted gross income, as losses will not be included.

The new adjusted gross income of the 1040 will flow directly to line 1 of the Form 1.

 

When filing your return, submit both versions of the federal income tax return, plus the schedule calculating the session method."
