Form 5329-T is TurboTax's designation for the Form 5329 for the person whose name is listed first on the tax return, the Taxpayer. Form 5329-S is TurboTax's designation for the person whose name is listed second on the tax return, the Spouse. Forms 5329 are individual forms, not joint forms, so there is a separate one for each individual on a joint return. TurboTax automatically prepares and includes the corresponding Form 5329 for the individual that needs it.
Forms for both are not identical in calculation and reporting of the penalty.
If you and your spouse are both calculating a penalty this year, then the calculation for each spouse will be unique to that spouse‘s tax facts.
