It is a good what if something does go wrong or if you delete TurboTax in the future and it does not update when you have reinstall it.
Sometimes using the manual update does have the installation problem that the download versions might have.
Not sure how far back TurboTax servers keep previous versions.
I was curious so I checked of the other software competitors and they have manual updates for Fed and individual states. (Hope statement doesn't ban me.)
