Upgrading

Hi, I've never been so frustrated with Turbo Tax. I purchased a cd/download version of 2021 Premier Turbo Tax from Amazon which I have used for the past three years.  In the past I have been able to talk with a tax expert. After all morning on the phone, I am told I have to purchase an upgrade to live, but I am unable to do this. I believe I read somewhere that one cannot get an upgrade if using this format? Help!
