It is most advantageous for the lower income to claim our combined medical expenses. Every time I open the 'optimizer' page, the program recomends claiming on my spouse's return (correct, she has the lower income). When I move on in the return it automatically changes it to my claim, resulting in a lower refund. Even when I go back and select the option of my spouse's return, it changes it to my return. The expenses are more than 3% of my spouse's income but less than 3% of mine. How do I get it to claim the medical expenses to my spouse's return not mine?
