How to force TurboTax to use charitable donations on spouses return instead of optimizing and claiming them against mine, in our joint return?

I'm using TurboTax Home and Business 2016.  I am in a common law relationship (a number of years now), so our returns are done together in TurboTax.  My partner made some charitable donations and I didn't.  I am the higher earner (with more tax payable) and TurboTax is optimizing the returns by adding the charitable donations to my return.  How can I force TurboTax to claim the charitable donations against her taxes, so she will get the credit in her refund?
