Q.Must We Replace Our Garden Soil?
We used a Fire Ant killer in our garden and later learned that it wasn’t suitable for edible treatments. Must we replace the soil or will we be able to turn-over/mix with the other soil in the raised bed box (5X8x1)?

Look carefully at the labeling and it should state how long it is effective in the soil. Most pesticides break down rather quickly. If it was a systemic product, those can last longer. You can also check the EPA website for info about the main chemical used in the product.
I would think that incorporating plenty of compost into the soil would diffuse any remaining chemicals.
