What Federal Tax forms do I need to add to my CA State Tax form?

I believe you mean that you have federal tax reporting forms such as W-2 forms and 1099 forms and you want know which ones you have to enter on your state tax return. If so, you enter those forms in the federal section of TurboTax and they get added automatically to your California tax return, so you don't need to add them separately to your state tax return in TurboTax.

The answer that was given is my understanding of what should happen  ( i.e. the State tax forms are automatically added by Turbotax). However in my case that did not happen and I had to make a copy of the forms I figured I needed and add them manually. Hence the question.
