Where can I find directions for IRA Withdrawals for NJ taxes?

Under NJ IRA Withdrawals I have my amount from a non-contributory IRA, as well as my inherited IRAs.  I took our teh RMD of about $8000.  I have several hundred thousand left over teh upcoming years.  The money is growing in an IRA investment account.  How do I handle Unrecovered Contributions, 3 year rule, general rule, etc.  I see no explanation at all.  (BTW, this is the worst version of TT in teh 15 plus years I have been using it.  It won't save.  It leaves me to guess what to do next in several places.  Some links are dead.  ... a real mess).
