I too am receiving "File Corrupted"
I sat down today to begin my taxes. I installed from the DVD purchased at Costco, then allowed the online update to occur.
I created a new return that had nothing but my name in it and saved, then closed TurboTax.
Reopen the just saved file ... FILE CORRUPTED.
Rinse and repeat 3 more times, same FILE CORRUPTED.
In any case, After re-installing many times I still get FILE CORRUPTED.
I tried to do an online install instead of using the DVD and TurboTax rejected it because it was already registered. Of course it was registered, I registered it!
I just tried the "Superpatch" available from "https://ttlc.intuit.com/community/updating/help/manually-update-turbotax-for-windows-soft[product ke..."
I now have a tax file that can be reopened, although all attempts to import last years data fails and creates a file that is corrupted.
Apparently if I now create a new return, without imports, it seems to be working but at this point I don't trust it.
