@RobertB4444 Regarding your answer to Question 2.
In California either all of the interest is exempt or none of it is. The determination depends on the percentage of California and Us obligations in the fund. If not over 50% then none of the interest is tax exempt.
See page 5. Exempt interest mutual funds.
