After you file

You can file an amended return using the tool that Turbo Tax provides.  It is your property and it can assist you in correcting the error.  Must be most unsettling for you, but mistakes happen and this is easily fixed. That said remember you are dealing with the IRS and resolving the problem will, no doubt, take a good deal of time to be remedied. They are slow, but the majority of folk who work for the IRS are empathetic to us and try to work with a system that is badly in need of reform.
