  We investigate $U_A(1)$ breaking above $T_c$ in terms of the Dirac spectrum
on configurations with (2+1)-flavors, using the HISQ action. The strange quark
mass is at its physical value. We use several light quark masses corresponding
to the Goldstone pion masses in the range of about 115 -- 230 MeV on lattices
of size 32$^3 \times$8 and 48$^3 \times$8. We calculate the 100 lowest-lying
Dirac eigenvalues at temperatures below and above $T_c$. We investigate the
volume dependence of the Dirac eigenvalue density to determine whether there is
a gap around zero, which can appear if $U_A(1)$ symmetry is restored in the
chiral symmetric phase. We also investigate the quark mass dependence of the
Dirac eigenvalue density at zero and check whether there is a linear behavior
that would signal the $U_A(1)$ breaking above $T_c$.
