Thank, Lisa. However, I'm not sure if I explained the problem correctly. As an example, the client received a Form 1099-INT showing $1,000 in Box 1. This will flow the $1,000 to the state (California) tax return. However, of the $1,000, the sum of $900 was from California bonds that are taxable for Federal Income Tax purposes, but Exempt from California in come tax. The solution you suggested will not work in the example I just provided.
