@SteamTrain Well, I am having the exact same issue with Chrome. Cannot download any of the updates except the 2017 Manual Update. Using Edge I can get them all. So it definitely looks like something on the TurboTax side preventing the use of a Chrome browser.
I also have the same problem using Chrome versus Edge when trying to download the 2019, 2018 and 2017 amend software from this TurboTax website - https://turbotax.intuit.com/personal-taxes/cd-download/amend/ty17/
