Where Is This Distribution From?

I have an IRA that I took a qualified distribution from.
The IRA is from a 401k that I rolled over three years ago.

What answer do I choose when asked "Where Is This Distribution From?"
The word "Other" is confusing me in the second choice. Otherwise
I'm pretty sure I chose "Other IRA distribution"

 

Pension rollover account
Other IRA distribution
Neither of the above
