Error code 2894 refund for defective TurboTax

At one time TurboTax was giving refund on their defective programing.  I had problems completing the form and now are turning to complete the form.  Now that form is no longer available.  I had to pay $169 to have my taxes done by a competitor.  TurboTax has no way to contact them.  I have used their programs for over 10 years and this is the first time I have gotten a defective program.  (I should not have to modify my computer to compensate for their programing error.)  As a protest, I am no longer going to use TurboTax.  I recommend other users do the same.
