Q. How could I say that I pay more than 50% of her living expenses?
A. You can't. Clearly your daughter is providing more than half her own support and cannot be your dependent.
Q. What would be a situation where I could claim her?
A. She put her $26,000/year income into savings and investment. instead of spending it on living expenses. Example: she lives at home and you provide all the room and board. The incidental personal stuff she buys, for herself, adds up to less than half her support.
