No Tax Tools as of April 1?

I just got off the phone from an hour long call with IT, asking why I cannot import my 2023 desktop return onto the 2024 online platform.   Apparently the answer is they turned off this option on April 1!! Why on Earth would the company do that? I have been an avid supporter of Turbo Tax for years and cannot understand why ANY options to make life easier for customers would be turned OFF.  This is the only complaint dept i could find, so I'm posting here and anywhere i can find to state how dissatisfied I am.
