It looks like the tax exempt dividends (1099 DIV, box 12) is not taxed by the federal government on my TT return. However, that full amount was added back in on my Oregon state return (Schedule OR-ASC, line A5). If half of that amount from box 12 was a US govt security ("Ishares Trust US Treas BD ETF", with detail indicating it was Nonqualified dividends), is that half portion also deductible from the addition that was made on the Oregon return?
