Sometimes the column E amount requires adjustment. Does your CA return include CA Schedule D (540NR)?
See this:
"Full-year nonresidents or part-year residents complete Schedule D (540NR), California Capital Gain or Loss Adjustment, and the Schedule D (540NR) Worksheet for Nonresident and Part-Year Residents, in order to complete column E on Schedule CA (540NR)."
