I filed form 4868 for an extension directly with the IRS for my 2019 return. Do I need to do anything on TurboTax when I submit my return for Federal or State (WI)?

"If you have an extension for filing your federal return, this automatically gives you a 6-month Wisconsin extension, provided you attach a copy of your federal extension application to your Wisconsin income tax return." but I don't see a way to do that on TurboTax.

I have a PDF of the form that I submitted and was accepted.

You will have to print and mail the state tax return if a copy of the IRS Form 4868 is required to be included with the state tax return.  

The federal tax return does not need the Form 4868 attached since the IRS already knows about the extension for your tax return.
