If you rolled funds from a 401K into an Individual Retirement Account then the IRA/SEP/SIMPLE box would be checked because it IS an IRA. So there is no cause for concern there.
It may cause you concern in New Jersey because it is taxable. TurboTax is treating it correctly on the forms. If the money had stayed in a 401K then it would be different. But it did not and it is an IRA now and New Jersey taxes those. The contributions prior to 1984 don't apply here because you rolled everything into an IRA.
