The basis of a Traditional IRA is the amount of non-deductible contributions you made to that IRA.
As the IRA was a rollover from your 401(k) plan and you made no contributions since the rollover, the basis is 0. This is because all your contributions to your 401(k) were made with before-tax dollars.
