Turbo tax incorrectly calculated my income how do I correct it after I have filed

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.

If you want to make changes or add a document to a tax return that has already been submitted, you should follow these guidelines. 

• You must first wait until the initial return is completely processed. 
• You will have to use the same TurboTax account that you used for the original tax return. 
• Once you begin your amendment, you'll see your original return.  
• The refund calculator will start new at $0 and only reflect the changes in the refund or tax due 
• Only make changes to the areas of your return that need amending. 
• You have three years from the date you filed your return or two years after you paid the tax due (whichever is later) to file an amendment
