@tfgatlin Really appreciate the response. As far as I can tell, the only way to carry 1f gains over to CA without overriding 1f and adding to box 3 is to add an adjustment to taxable interest on in the CA Interest and Dividend Adjustments Worksheet in Line 12 Column B. Others suggested that's what they did manually in some other threads but nobody replied what they used for the description in column a.
If you're saying the adjustment was made on the federal return so that Line 1 of the Interest and Dividend Adjustments Worksheet worksheet already includes the AMD, then the only way to make that adjustment is to adjust Box 3 of the 1099-INT since Line 1 of the CA form only includes Box 3 interest of the 1099-INT.
