Yes. You will claim a credit on your resident tax return for tax paid to another state. California has a few odd rules allowing to you claim the credit on the nonresident return, but that doesn’t apply to New York residency.
In the original question, the Op either made an incorrect assumption or had RSUs or other income that was double taxed by California and New York.
The OP said she made $12,000 in NY ($2,000 x 6), but then said her NY income was $18,000, or half her federal income. That would be incorrect if she only made $12,000 based on her pay stubs. NY only taxes you on what you actually earned. It does not tax you on total federal income divided by the months you were a resident.
The second case is if the OP had RSUs or other California-sourced income that was earned as a result of CA employment but received while living in NY because the OP worked for the same employer. In that case, the OP could claim a credit on the NY return, because the amount is included in both CA and NY income.
