Calculating amount for CA less than 50% tax exempt

I live in California. This year I received tax-exempt interest from a variety of municipal bonds. My CA tax form is asking me how much of this interest is from "funds with less than 50% of their assets invested in California and US obligations".

 

Here's the info on my tax-exempt interest from my brokerage's 1099-INT:

State of residence (CA)

  • Tax-exempt interest: 950
  • Accrued interest paid -44
  • Bond premium- covered lot -461

Other states

  • Tax-exempt interest 6299
  • Accrued interest paid -2341
  • Bond premium- covered lot -1678

 

Two questions:

 

1) Is the proper amount to report on my CA tax form as "less than 50% tax exempt interest" 4,621 (6299 minus 1678)?

 

2) Does it matter that these are individual bonds instead of "funds"?
