I filed my taxes using TurboTax online for both Federal and Wisconsin. I am looking for a place to verify the date that my WI taxes will get paid, but cannot find it.

Within your TurboTax documents you can access worksheets. 

On the State worksheet, the payment information will be listed. 

If you did not print the worksheets with your tax file, you can go back into your TurboTax account and print the additional worksheets.
