Error 10250: TurboTax encountered an error when saving or loading your data file occurs when saving your return in TurboTax software for Windows.
Solutions
First, save a copy of your tax return with a new name (avoid using special characters in the name, such as &, -, @, etc.) and use this new copy from now on.
If that doesn't work, continue through the TurboTax Interview until you reach the Thank You for Using TurboTax screen, located on the File tab. Then, select Save (or Print) from the File menu in the upper left corner of your screen.
You can also try saving your tax return as a PDF file to work around this issue.
