Tax exempt interest from California sources of $xxxxx transferred from your federal tax return.

Turbotax has this statement in the Subject box above when I worked on the CA return, which is followed  with a question: "Is any of this interest from funds with less than 50% of their assets invested in California and US obligations? 

 

I looked at all my 1099-INTs from various financial institutes and could not figure out how the amount $xxxxx was arrived at.  I need to determine which investments contribute to the amount and which of them are  qualified for the 50% rule.  Is there a worksheet containing the information?

 

Thanks!
