I experienced this also, but with a twist. I'm completing a return for my deceased father. I had all information entered last week, resulting in a refund of all his taxes paid. I went in today to correct a slight error in the income tax withheld and all of a sudden he owes a very large penalty. I did not change any other numbers. I agree that something in the programming may have changed over the weekend. Even if I indicate the entire distribution applies to RMD, it still calculates the penalty. I have to change the RMD due by December 31, 2024, to zero in order to have the program calculate correctly. I did not have to do that last week.
