So, do I amend my 2016 return and send it, and complete my 2017 and send it at the same time? Or do I need to wait for 2016 to be accepted first? If I do amend 2016, it will return some money. Do I then list that changed value for 2017 and my federal/state returns, or do I file 2017 with the original values and then amend 2017 once my 2016 is accepted?
