Thanks DavidD66. Though unable to locate details of the CA state subtraction for Treasury interest in the return PDF, I now believe that in my case the subtraction is calculated from one 1099-INT as Treasury Interest (box 3) less Treasury Bond Premium (box 12) less Accrued Treasury Interest. Unfortunately, TurboTax seems to be splitting the Accrued Interest proportionally between Treasury (box 3) and non-Treasury (box 1) interest even though all Accrued Interest on this 1099-INT is actually Accrued Treasury Interest. How can I get TurboTax to treat all Accrued Interest on this 1099-INT as Treasury interest?
Thanks, DW (desktop TurboTax Deluxe)
