I made about 8,000 in 2016. I don’t have any of my W2’s or any proof of income. (My area was flooded) I didn’t file in 2017. Can I still get the EIC without income proof?

This is also my FIRST time filing. I don’t have any of my W2’s except for the one I entered that I got in 2017. It’s showing I was eligible for the EIC. And it got accepted. Am I in the clear or should I be worried?
