Thank you for your response. It looks like jointly, with my income included on the Social Security income worksheet even with the various deductions the total is well above the 85% of the SSA Benefit. Separately, with just her SSA income and not being allowed to use any of the deductions, it calculates out to be just about half of the 85%. So a significant difference. With my income, more of her SSA is taxed. Without my income, less of her SSA is taxed. Again, that is if I am following the rules correctly, and she does not have to include my income in the worksheet on her separate return.
