<prompt> Human: I just noticed that I had the wrong SSN for my wife ever since we started filing taxes 2012 on my 2014 taxes. Only one digit is wrong. How do I fix this?Edit: only for 2014; I had it right for 2015 and 2016. We did get our returns and didnt have any problems since. Do I still need to file the 1040X?  <response>: No big deal. Refile with a brief explanation.
