  In this work, we study the magnetic-impurity resonance states in
superconducting phase of twisted bilayer graphene for different pairing
symmetries. Using the two-orbital model proposed by Yuan and Fu in [Phys. Rev.
B 98, 045103 (2018)], we find that when the impurity is located at one site of
the emergent honeycomb lattice, the spacial distributions of the resonance
states will break both the threefold and twofold rotation symmetries of $D_3$
group for pairing symmetries which belong to the irreducible representations of
this point group. When the magnetic impurity is located at the center of the
emergent honeycomb lattice, the appearance of resonance peak at the position
close to the impurity can be considered as a strong evidence of non-$s$-wave
pairing.
