Capital Gains on Real Estate when part-time resident in two different states.

For California State taxes declaring capital gains on real estate:

There's a point where there's a choice of choosing "Sale by Sale" or "Choose by allocation if you know the amounts".  When I chose the first one it did not carry the capital gains amount over to column E on form CA (540NR).  Each option gives me a different amount of taxes that I would have to pay.  It is not clear to me which option I should choose.  It would have been nice if TurboTax had explained the options better because this has caused me a lot of angst.  Can you please shed some light on this.  Thank you.
