Retirement tax questions

"I thought that the Roth 401K would have contributions, conversions/rollovers, and earnings for a general case."

 

Correct.  Basis in contributions, basis in In-plan Roth Rollovers, and earnings.  Your basis in your designated Roth account in the 401(k) comes entirely from the IRRs and everything else in the account is earnings.
