you can’t overturn an electoral college vote.. no precedence for it.

Actually, you are not correct.

The year was 1876, and Congress voted on straight party lines (one vote per state) and chose a President one day before the expiration of President Grant's term.

Technically they were not "overturning" the electoral college vote, they were just not accepting it and were replacing it with their own vote.

The Electoral College failed to decide a winner in the 1876 election so it was thrown into Congress, a different scenario altogether. In any case. the Electoral College wasn’t overridden, there is no way for that to happen.

I assume that if some information were to come before Congress AFTER the EC had chosen a winner, that the person was somehow ineligible Congress could impeach, them, but that is all. I know of no Constitutional provision to nullify the result of the EC vote.
