@elizaalmstedt P0420 is the "Catalyst System Efficiency Below Threshold (Bank 1)" error code. Causes for this could be any of these (and many more):
 
A damaged or failed oxygen / O2 sensor
 
Downstream oxygen sensor wiring damaged or connected improperly
 
Damaged or leaking exhaust manifold / catalytic converter / muffler / exhaust pipe
 
Cylinder misfire
 
Most common likely cause for your model and year Honda would be a failed catalytic converter. That would require a replacement.
