Corrupt file after State update

[user17748241993]

I am using TurboTax Deluxe + State desktop version. I'm trying to file a second Federal return. I've entered the information 2x and each time the file will not open and both files return a message that states "Looks like your tax file is corrupt, we're having trouble opening your return." The first error happened after updating TurboTax so I created the second file. My initial federal and state return file opens fine and I can continue to work on it, but the other will not open. I've tried opening from a back-up as well, but that doesn't work either. Any help is appreciated. @corrupt, @corrupted

To recover a corrupted TurboTax file, first search your computer for backup files (.bak or .tax202X). In File Explorer, search for *.tax202X or *.bak to find auto-saved or backup copies, then remove the .bak extension from the filename to open it in TurboTax.

Look for a PDF copy of the return you may have created, which can be used to re-enter data.

Try opening the file in a different TurboTax version, updating the software, or running a disk check (CHKDSK). 

If you continue to experience the same problem after following the troubleshooting steps, please contact TurboTax customer support for further assistance.
