Gauges vary and your's might not be accurate, so air them up to 40 or so and the light should go out on it's own after some driving. (~37 cold is normal)
Are you sure the seller didn't pull the TPMS hardware and replace them with regular $4 valve stems? Look closely at the stems, they should be an exact match to those in your SR-A sport wheels.
The system resets itself, so pressure above about 32-33 psi and a little bit of driving should do it.
