Has anyone else been having an issue with the 2024 1040 program over-calculating the underpayment of estimated tax penalty?  My clients who underpaid are receiving notices that their balances due or refunds have been changed because the amount of the penalty calculated by IRS is significantly less than what ProSeries has calculated.  This issue goes all the way back to returns filed in April, right through to returns filed in October.  I called ProSeries in the summer about this and it seems they have done nothing about it.
