We are telling you that TurboTax does not calculate your interest or penalty owed for you. It is only calculated by the IRS when they receive your return and when they receive your payment for the amount on line 37 of your Form 1040. TurboTax never knows when the IRS is going to receive your Form 1040 and TT never knows how, when or even if you paid your tax due. The penalty and interest are not calculated until the IRS has your tax form, and your payment in hand----based on the date the IRS receives it.
