401K distribution; how to classify for tax purposes based on choices provided in Turbotax

after entering the 1099, it's asking me to select the source of the distribution and any other NJ information

Choices:

 - Military benefit or survivors benefits

- Disability benefits (under age 65 only)

- Three Year rule pension or 401k benefits

- General rule pension or 40k benefits

- None of the above

 

Military and disability benefits don't apply to me.  I don't know which of the other 3 to select.  If I select "general rule", it gives me a refund on my state of NJ return,  I don't think it's three year pension rule based on the defnition.   If I select, "none of the above", the amount of the distribution becomes taxable in NJ.  Help!!
