All the heavier elements were created in a former star that went supernova. The solar system formed from the gas/dust after that.

The heavier elements being formed in our sun now are going to stay there until something can tear it apart.

Some will be ejected back into space when the aged Sun becomes a planetary nebula (with a white dwarf at the center).

Until several billion years in the future, our sun will create no element heavier then helium.

IIR, our sun's mass is far too low to ever create any element heavier than carbon.
