There is no way to enter preparer information in TurboTax. The preparer section at the bottom of Form 1040 is for a paid preparer. If your husband didn't pay you to prepare his tax return, you do not list yourself as the preparer. If he did pay you, you cannot use TurboTax. TurboTax is only for self-prepared tax returns. It cannot be used by a paid preparer.
