  In this note, we complete the classification of quasi-alternating Montesinos
links. We show that the quasi-alternating Montesinos links are precisely those
identified independently by Qazaqzeh-Chbili-Qublan and Champanerkar-Ording. A
consequence of our proof is that a Montesinos link $L$ is quasi-alternating if
and only if its double branched cover is an L-space, and bounds both a positive
definite and a negative definite 4-manifold with vanishing first homology.
