Can I add my 2016 w-2 to my 2017 tax return? I used to live in GA in 2016 but moved to TN in March 2016.

No, the government does not allow you to combine Tax Years. Your 2016 W-2 must be filed on your 2016 return. If you have already filed that return you would need to amend. If you have not yet filed a 2016 return please use our prior year products to complete that return which will need to be mailed. If you have already paid for your 2016 fees please contact customer service. Only the current tax year can be filed online. https://turbotax.intuit.com/personal-taxes/past-years-products/
