Just bought Turbotax 2021 Desktop. How to upload W2 PDF?

Never used Turbo before, previously used credit karma and I always just upload PDF to autopopulate all the fields. My wife who used Turbo free edition did that too online.

 

But my tax this year is more complicated so I bought Turbo premier off amazon. And I dont see a function to upload PDF anywhere. It asks me to important with control # but always gives me error... Does this function NOT exist on Turbotax desktop? Seems difficult to believe if this is true... since its so easy to implement
