This actually works.
I found this a couple years ago and it worked for me. New Mac today, this nonsense started up again.
Launch TurboTax. Let it update (grrrrrr...)
When open, click on the TurboTax menu. Look at Check for updates and press your Option key. This will change to Download Latest Updates... Click on that and it will show there's an update available !?!?!? Click and let it run.
This fixed it for me today — again. It would be nice if Intuit would fix it, however.
I don't have a Win machine but it would surprise me if the Alt key didn't accomplish the same thing.
