Filing status

[rodrialb000]

I have a quick question, is it now a requirement to provide the previous tax return 2016 for the current tax return of 2017? I filled but I am just not sure if I filled correctly. On the filled status it shows in progress but I don't know if I still need to provide it if I was getting it mailed?

How do I keep in the loop on how long my or where my status is on receiving my tax money?
