Retirement tax questions

I'm preparing my return and was shocked that I need to pay NJ tax on my 401K rollover.  I just realized from reading your post that there is a difference between simple IRA and rollover IRA.  Can you tell me what is the difference?  I thought that if it's not a Roth IRA, then it is a simple IRA.  After it's rolled over, it becomes Rollover IRA.  The instructions asked if I rolled over to a simple IRA .  So it seems to me I should answer yes (since it's clear it was a rollover)?   

 

Also, how do I go back to the step by step interview?  I can no longer find that.

 

Thanks!
