@Critter-3: I appreciate the feedback. However, I e-filed my VA return (with direct debit payment) the same day that I e-filed my Federal return (before the filing deadline), so I don't believe that timing of the return is an explanation. (Also, VA did not charge me any interest -- just the under-withholding penalty.)
If the VA tax authority calculated a penalty using the information filed, then TT needs to incorporate that calculation into its VA state return logic. I would like Intuit to investigate this issue; either the VA State product needs updating, or else VA improperly assessed my penalty.
FYI, I see a separate posting that suggests that TT has a related problem with its NY state return product.
