Line 6 on Form 2441 is the qualified expenses you have paid for childcare after reducing the amount by any employer benefits. This carries over to your Wisconsin return for up to $6,000 for two or more children. TurboTax is calculating the credit correctly in accordance with the Wisconsin instructions.
You are not getting a double benefit if you paid $11,000 in child care expenses, had $5,000 reimbursed by your employer and receive a credit for the other $6,000 on your state and federal taxes.
Since the adjustment is new this year to not conform with the federal changes, how it was calculated in prior years may not reflect how it is calculated this year.
