  We present the results of the second year of exoplanet candidate host speckle
observations from the SOAR TESS survey. We find 89 of the 589 newly observed
TESS planet candidate hosts have companions within 3\arcsec, resulting in light
curve dilution, that if not accounted for leads to underestimated planetary
radii. We combined these observations with those from paper I to search for
evidence of the impact binary stars have on planetary systems. Removing the
quarter of the targets observed identified as false-positive planet detections,
we find that transiting planet are suppressed by nearly a factor-of-seven in
close solar-type binaries, nearly twice the suppression previously reported.
The result on planet occurrence rates that are based on magnitude limited
surveys is an overestimation by a factor of two if binary suppression is not
taken into account. We also find tentative evidence for similar close binary
suppression of planets in M-dwarf systems. Lastly, we find that the high rates
of widely separated companions to hot Jupiter hosts previously reported was
likely a result of false-positive contamination in our sample.
