Thanks for the detailed response on this, Mike. I checked in Excel and the accrued interest pro-rated for the 1099-INT Box 3 value comes within a few cents of the TT CA subtraction (gotta wonder why it would be even a few cents off, but...). Fortunately this 1099-INT only has values in Boxes 1 and 3, so as a quick test, I zeroed out the Box 1 value and now Line 1, Column B on the CA Interest and Dividend Adjustment Worksheet shows the full value of my accrued interest. Now all I have to do is split this 1099-INT into ox 1 and Box 3 version, and I should be good to go.
