My daughter is a full time student in MA, last summer she earned $9000(w-2) for intern, How can I use MA state income tax as a credit for CA?

After you do the Federal return, do the non-resident MA return, and then last do the resident CA return.  

The resident CA return will tax you on all income earned, and then give you a credit for taxes paid to another state.  So make sure in the CA interview section you cover the credits and go over the credit for taxes paid to another state.
