Wisconsin definitely still has payment vouchers for returns that are filed electronically: DOR Payment Vouchers
The first sentence: "If you filed your return electronically but pay the Department of Revenue by check, you should include a Payment Voucher with the check you mail." Clicking on the appropriate link at the bottom of the page takes you to the applicable interactive voucher printing screen you allude to in your response.
My point was that TurboTax used to print Wisconsin Form EPV (Electronic Payment Voucher) for e-filers, but that form is now "unavailable". That actually makes sense given that Form EPV is no longer used. What doesn't make sense to me is TurboTax not supporting Form PV. So... my question is: Is TurboTax going to support Wisconsin Form PV and, if so, when? My guess is the answer is either "No", or "Yes, but not for this year" given how close we are to the deadline.
I do think you are right about their thought process: Wisconsin definitely wants payment electronically not by check.
P.S. Given that I had not gotten a response from anyone at TurboTax after 2 days, I did go to the WI DOR website and print a voucher. It still says they are having "technical difficulties", but it seemed to work. 🤷♂️
