2013 Kia Soul - TPMS

I have a 2013 kia soul.tire pressure light came on.i put the right amount of air in the tires,but the light is still on.how do I correct this so it goes off

If all the tires have the proper amount of air, the light may take a few miles to turn off.

Does your vehicle have a TPMS sensor in its spare tire?
If so, did you check the pressure in the often-overlooked spare?

Mostly because it is really unpleasant outside today I looked at You Tube and there seems to be several videos on resetting the TPMS . Of course the dumb question is did the Op use the body placard as a guide for the tire pressure.
