I extended my US return by making an extension payment electronically, per the following from Form 4868 instructions:
You don’t need to file Form 4868 if you make a payment using our electronic payment options. The IRS will automatically process an extension of time to file when you pay part or all of your estimated income tax electronically.
Wisconsin accepts US extensions, but wants a copy of Form 4868 (none exists), or a statement that you are using the US automatic 6 month extension. I checked the box in the Wisconsin input that says I have a US extension, but I see nothing in the filing forms that is the statement Wisconsin requires. I also see no way to add a statement to the WI return. If I paper file Wisconsin, I could create a statement and include it, but I find it hard to believe that is what Intuit intends.
The Form 4868 extension request will be included in the PDF download if you used the TurboTax e-file for the extension.

If you used the desktop CD/Download editions installed on your computer, the only copy of your tax data file and any PDF's will be on the computer where the return was created. TurboTax does not store online any returns completed using the desktop editions.
If you did not file an extension and none is in the .taxfile when you access it then you would need to provide the state a statement per the state extension regulations. If one is needed you will need to mail the return. Personally I would simply file the return and if you get a notice you can respond at that time with a statement.
As per your original post, you paid with your request for an extension.
That amount should appear on Schedule 3 Line 10.
A non-zero amount demonstrates that you requested a federal extension.
( I'm assuming TurboTax attaches federal return if you e-File Wisconsin return ).
However, the WI instructions still ask for a confirming statement with statement of intent.
