  Fractionally filled Chern bands with strong interactions may give rise to
fractional Chern insulator (FCI) states, the zero-field analogue of the
fractional quantum Hall effect. Recent experiments have demonstrated the
existence of FCIs in twisted bilayer MoTe$_2$ without external magnetic fields
-- most robust at $\nu=-2/3$ -- as well as Chern insulators (CIs) at $\nu=-1$.
Although the appearance of both of these states is theoretically natural in an
interacting topological system, experiments repeatedly observe nonmagnetic
states (lacking FCIs) at $\nu=-1/3$ and $-4/3$, a puzzling result which has not
been fully theoretically explained. In this work, we perform Hartree-Fock and
exact diagonalization calculations to test whether the standard MoTe$_2$
moir\'e model with the (greatly varying) parameter values available in the
literature can reproduce the non-magnetic states at $\nu=-1/3$ and $-4/3$ in
unison with the FCI at $\nu=-2/3$ and CI state at $\nu = -1$. We focus on the
experimentally relevant twist angles and, crucially, include remote bands. We
find that the parameters proposed in [Wang et al. (2023)] can nearly capture
the experimental phenomena at $\nu=-1/3,-2/3,-1,-4/3$ simultaneously, though
the predicted ground states at $\nu=-1/3$ are still mostly fully-spin-polarized
and a larger dielectric constant $\epsilon>10$ than is typical of hexagonal
boron nitride (h-BN) substrate $\epsilon\sim 6$ is required. Our results show
the importance of remote bands in identifying the competing magnetic orders and
lay the groundwork for further study of the realistic phase diagram.
