Deductions & credits

On my Oregon return, TurboTax chose the higher standard deduction for me over the lower itemized deduction. But, if I am reading the Oregon instructions right, since I am MFS and my spouse itemized on his Oregon return, it looks like the standard deduction should be $0 and I should choose to itemize. Am I looking at this incorrectly or has TurboTax chosen the wrong deduction for me on my Oregon return?
