How can I claim the maximun allowable chilcare deduction for a disable child ($11,000) IF I do not claim the disability tax credit? Turbotax only allows $5,000 deduction

I'm not claiming the Disability Tax Credit (my ex-wife does), but I do claim all the childcare expenses, however, turbotax does not allow me to claim the maximun deduction ($11,000), but just $5,000
