If you rolled it into a Traditional IRA then, if you have non-deductible contributions in any Traditional IRA, when it asks for the total 2016 year end value of *all* Traditional IRA's then add all Traditional IRA's, however, a Traditional TSP is not a Traditional IRA. A Traditional TSP can be rolled *into* a Traditional IRA by a trustee-to-trustee transfer and would probably be reported on a 1099-R with a code G in box 7.
