Hilchos Maasei Hakarbanos 9:12

The bread that was waved from a thanksgiving offering or a nazir’s ram and the cooked foreleg are also eaten by the kohanim; the rest of the bread and the rest of the meat are eaten by the ones who brought the korban. The bread that was waved with the breast and thigh is called “that which was raised from the thanksgiving offering.” The cooked foreleg and the breast, thigh and bread that were waved are called “that which was raised from the nazir’s ram.”

Hilchos Maasei Hakarbanos 9:13

There is a doubt as to whether the bread that was raised from the thanksgiving offering is considered terumah or not. Accordingly, one is not subject to a divinely imposed death for eating it, nor must one repay it with an extra fifth. Similarly, a mixture containing it isn’t subject to the laws of a mixture containing terumah.
