Error reading your return from disk TT403

[WarningU2]

Back on Feb 25th I completed my 2018 Cdn taxes but did not netfile as I am waiting for one final T4 slip.   I saved the return and all was good.    

Yesterday I referenced the file to check some numbers and closed the program out.   I never changed anything and the file shows last update Feb 25th.    

This morning I wanted to add the data for my final T4 slip and when I went to open the file I am getting a TT403 error.   I referenced the error here and found https://ttlc.intuit.com/questions/4643233-tt403-error-my-2018-file-was-okay-a-few-days-ago-when-i-ac... so restored from my backup and the same error is experienced.   There is no versioning (from an incremental backup) because there was only ever one version.  The ttbk file is not found.  

It looks like I am pooched and will have to redo all my work ... urgggh!   I've been using TurboTax for years and never had this happened before.   My PC is fine.  No other files are corrupt.   I see that others are posting about a similar error.   Is it possible a recent update has corrupted earlier created files?    When I did open the file yesterday I did update the program but never saved the file after opening, just exited out.  I didn't change anything so thought it was fine but now wondering if the update has screwed me.   

I am posting this just sharing my experience to advise others if you open to always save the file.  Don't just exit out the program

Thanks for sharing your information on what you experienced.   I also save a backup copy after every session to a thumb drive as well--just in case.

You have posted your thread in the USA TurboTax community forum.  (yes, the sites are too similar, and we have complained to TurboTax about it.)

Here is the Canada TurboTax AnswerXchange community forum:

Thanks ... yeah I just stumbled onto the Canadian site too.  Sorry for posting.   Feel free to delete my post.  Google brought me here when I searched for the error.    Would be nice if the site actually said this is the US community forum.     Now off to repeat all my work.   This is a super annoyance that it was corrupted somehow.

It might still help someone who searches for that error.  We have complained for some time that the 2 sites are too similar.  All they have to do is add a country's  flag or maple leaf or something, which would help.
