It depends on which version you are using. If you are using TurboTax Online Free, TurboTax CD/Download Free or TurboTax CD/Download Basic, there are no optimizers included. TurboTax CD/Download Free and TurboTax CD/Download Basic just have forms and no interview questions.
You would need to get Standard or higher to get optimizers and the credit search.
