Washer fluid will not cause the SES light to come on (though I think it causes it's own light to come on).
Best place to start is autozone or a similar parts store. They can check for codes for free and let you know what's causing the SES light.

Went to auto and got a read : the code is PO420
1 They said this could be Catalytic Converter defective Failure possibly due to #2,3 or 4
2 Engine Misfire or running condition
3 Large vaccum leak
4 Engine Oil leakage into exhast-valve guide seals, piston rings
Had complete diagnostic ran when car was purchased in Feb. The car runs very smooth and sounds so silent, that you can't hardly hear it running.
Had oil change and all engine fluids flushed and filled, in Feb as well.
It has new computer and all new wiring.

ECU and wiring? Flood car? How are shocks and suspension usually a 4-6 year rehab cycle.

I doubt it's being caused by any of the reasons they gave, especially number 2, which you would definitely notice (car would not be running smoothly as you describe it if it was misfiring).
You probably just have a bad O2 sensor. It won't cause any major issues but will cause the car to fail emissions tests and could possibly cause the car to run less efficiently depending on what wrong signals the car reads from it. Not something that's super urgent if you just need to keep driving the car, but it's also not horribly expensive, so worth doing as soon as you can.
