For the Child Disability Amount Transfer, how do I change the adult claiming it? It is selecting my wife automatically, but I'm the one registered with CRA.

When preparing a coupled return, TurboTax Online automatically claims the disability amount transferred from your dependant on the spouse with the higher income (after deductions).

If you would prefer to have the deduction claimed on the lower income spouse's return, the returns must be prepared separately.
