Tried that several times. It keeps changing back to the incorrect value.

If you are filing with TurboTax online, follow these steps: 

• Check your internet connection.  Try to log out and sign back in the program. 
• Clear your cache and sign back into the program.  To clear cache, click here: Cache
• You may also try a different browser.  
• Then try again. 

Also try zero or one.  If remain unsolved, print out return and paper-file.  For explanations, click here: Correct AGI got rejected

Tried clearing the cache, and even a different browser.  The TT software is not working correctly.  If I have to mail it in then what good is your software..  I can add.
