I can't e file and I need to file by mail.

Hello, may I get clarification on what you mean by duplicated pages?  Did you print your whole return to mail and it printed it out multiple times?  Please respond here for further assistance. 

I had gotten a duplicate copy for my federal, but im assuming i have to attach it to my California return since it says attach copy of federal?

Correct ... if you asked for the CA return and a fed was included  then read the CA mailing instructions to be sure ...  

• After the return is open, click in the left menu column on TAX TOOLS, then PRINT CENTER.
• Then choose "Print, save, view this year's return."
