Thanks JMKCPA!
Following your reply I went into Turbotax.intuit.com to the "Do It Yourself - Doing taxes with Desktop software" link. On that page the "Download TurboTax software" link leads to the incorrect 2023 installer download. But using "Intuit Account - Desktop login" allowed me to enter the Product Key I received from Amazon and download and install the 2024 version.
Now I can plug in my estimates for 2024 and do some year end tax planning.
