State tax filing

Int and Div uploaded from Financial Institution. Posted correctly to Federal. Misclassed several line items as non taxable and instructed me to fill in reason code. Classification was wrong and T TAX wouldn't let me correct it on the form. After hours playing with it, finally got T TAX to clear the NH State Form.  Rechecked the Federal and didn't answer question on individual Int & Div income as to whether NH & other selected states treated some Int & Div differently.  T TAX then correctly classified all taxable and non taxable amounts but wouldn't let me access the reason code for a $20 auto uploaded item but told me it needed to be inserted. Finally, with the help of a T TAX agent, I was able to "GUESS" the reason code and enter it as he walked me through it.  This process took hours each day over several days delaying even the Federal return since I wasn't comfortable with that if T TAX couldn't even do a NH return (would have taken less than an hour to download NH forms and fill them out manually).  If TTAX can't do it, they shouldn't offer it.  Should rebate the entire price I paid to use them this year.  Total Rip off. Will be doing NH manually next year. Too simple to pay $50 for. Just carryover line items from Federal.
