Don't do anything. I stole this from another software site:

California Franchise Tax Board requires the federal return to be attached to the California return as follows: 

• Form 540: Federal return is required if federal return includes supporting forms or schedules other than Schedule A or Schedule B
• Form 540NR: Federal return is required for all Form 540NR returns

Required attachments are automatically included with any electronically filed Form 540 or 540NR, regardless of whether the federal return is actually being filed electronically with the IRS.

The return you are working on does not require a 540, so just let Lacerte do it's things. Good on you for asking about things you feel are not right.
