I had this problem after I purchased the desktop software. I went to the website and logged in using my previous credentials and started my return. I found nowhere to enter my license code. Then I saw someone else's comment and found my mistake. I had downloaded the TurboTax software and should have been accessing it through the newly installed 2024 Turbo Tax icon on my desk top. Once I did that, it brought me to a place where I could enter my TurboTax license code and proceed with starting my return without having to pay again.
