Since Intuit gives us no official way to do this, perhaps someone has found to where TurboTax downloads the files for State, and we can copy them out of these and save them for later manual installation on an offline computer?
(I looked around in %USERPROFILE%\AppData\... shortly after TurboTax downloaded and installed a State, and I don't find anything that looks obviously like a software installer for the State component of TurboTax).
