Retirement Income. Three Year/General method or Do Not Apply

I have two retirement related sources of income to report,  but I am not sure I am entering them properly.  One is a lump sum distribution received as an inheritance from a recently passed relative's 403b plan.  The other is a lump sum from my own 401k.  What are the proper classifications of these distributions?  Should they be marked as Three Year,  General Method or classified as None of the Above?
