This error usually occurs because your browser will try to download the file as an XML file, rather than a word doc. You can try the workaround below:
1. Send the corrupted Word file to your email account.
2. Click the attachment to open it in the Google Docs previewer.
3. Click "Open With Google Docs". The document should open and be viewable.
4. Click File -Download As - Microsoft Word (.docx).
5. Use Microsoft Word to open the document you just downloaded.
If that does not work and it was a copy you had saved, you can try pulling your return back up and download from your TurboTax account.
First, make sure you're using the same TurboTax account (with the same username) as in prior years. Otherwise, the below instructions won't work.
If you're signing in for the first time this year, we may ask you some questions before you get to the Tax Home screen where you can access your prior year returns.
If you need to find an account, our account recovery tool can help you find your User ID or password.
