Thanks @AmyC for staying on top of this thread. Again, the question is:
"Enter the portion of the net capital gain amount that you elect to include in investment income."
So just to be clear, since I am a full-time CA resident (with no carryback loss) then I should "elect" to include the entire capital gain amount in my CA investment income.
In this case I think a tip from TurboTax would be helpful regarding what the common response is from most full-time CA residents, especially when you are dealing with the very basic case of short term and long term capital gains stock sales.
