I am using the Premier version of TurboTax on my PC in order to prepare the taxes. I have added my credit card info to my Intuit account. I successfully efiled my son's federal return however when I try to efile my son's Mississippi return it will not go through and says I must call customer service. I've been on the line with customer service for over a half hour and they have no idea how to pay for the efile. How can I pay for the state efile fee and efile the Mississippi return?
