Revisiting W-4 Worksheet

After filing my taxes, my wife changed jobs. I can get back into my return in TurboTax, but I cannot figure out how to get back into the step-by-step guidance for the W-4 worksheet. How do I get to that so I can enter different information based on our new situation? (I can find the W-4 worksheet

in Forms, but can't figure out how to go from there to the Step-by-Step.)

Thanks!
