Solved
Where do I tell TurboTax that I do not want to claim her?
The short answer is if your daughter qualifies as your dependent she cannot claim herself on her own tax return. The question she will need to answer is can someone claim her, not will someone claim her. You can't move dependents between tax returns because it's beneficial to do so.
On the other hand, as epo points out, there may be a substantial question as to whether she really is your dependent or not. The questions epo asked need to be answered before any advice can be given on that point.
