So digging a little deeper and a little more about my situation. Etrade reported AMD on 6 of my bond redemptions (all held until maturity). All the rest of the bond redemptions were zero coupon treasuries all bought at a discount of course. None of the AMDs for the zero coupon notes were added to box 1f but were instead all accounted for in box 3.
The IRS treats all income held to maturity as interest income. Conflicting sources say CA does or does not count AMD if it's a treasury held to maturity. A more nuanced interpretation is that the difference between OID minus the actual discount is taxable and treated as ordinary income if your purchase price was at a deeper discount than the OID. At the very minimum, the FTB couldn't tax you if your price was OID or higher since you'd not be getting a discount greater than the what the Feds issued in the first place.
Etrade's 1099-B 1f doesn't take into account OID. It just counts the entire difference between face value minus price paid.
