My Turbotax instructions for mailing in my CA return says not to include W2 forms, but the CA 540 instructions say that I am supposed to. Can you please clarify which is correct?

I live in California.  On a CA state return TurboTax prints out a page with your W2 and other income and withholding information so you do not need to mail copies.  But if you do it does no harm. Except a little extra postage, maybe.
