Had a similar experience --- asked Turbo Tax to pay NC tax directly from my federal refund. Never heard if actually done, or not!! Refund was credited to my bank acct. mid=February. Accually included amount that was designated NC tax due!!! So, decided than rather than wait till NC tax was due, went ahead and sent a check, (ahead of due date).. Apparently more than "whoever" could contemplate how to handle this, check was cashed. Just now, on April 1, my bank account indicated a debit amount deducted from my acct. for the exact amount of NC taxes due! Long story made short - I have currently paid my NC taxes twice.! Wonder if anyone will eventually notice this double payment and send back some money??? (the life of internets, and no humans involved, I guess).
