After you file

I have a follow up question on this - I needed to make a change to the 2016 taxes to add in an additional expense. I downloaded and installed Turbotax as prompted. I entered my expense and it created the 1040x form which I printed out. From what I can tell, it also created a 1040x for 2017 online. Do I need to send in both 1040x forms?
