The Search function in TurboTax Desktop brings up a Digital Assistant that provides answers to questions. I just tried entering "apply federal refund to next year" in the Desktop Search and got answers about how to track a refund. The "Jump to" links are typically in TurboTax Online searches.
I will report that the Help article should be updated for Desktop users.
In TurboTax Desktop, go to Other Tax Situations, then look in the category Additional Tax Payments. Select "Apply refund to next year" by clicking the Start button next to it. Read the helpful information at the Learn More link.
