Can someone trace my Instagram account back to me?

[*]

I have an anonymous account on Instagram and this person keeps asking me to just say who I am, and I said I don't know you cuz I thought I didn't. Then he said well what if I told you I am ******* and he said my information. How would he know if I never told him? I'm freaking out

You need to be careful an close that account! What if he is a murderer or a terrorist or somethin? Close your account an nevar open it again! Be careful next time!

Although I personally don't know how to do it. Anything on the internet can be traced back to your computer IP address.
