quantum mechanics has shown us instant transmission of information thru quantum entanglement

Unless that's changed recently, you can't transmit information that way. You need information at the end about the measurement of the entangled particle, which has to be sent in a classical signal, limited by light speed.

But the information does come back to you instantly. It doesn't really have to travel though.

it requires a slow signal to verify, it does not change the fact that the information was present before the electrical signal reach.

the obviousness of this makes me question your motives for confusing it such

No, not information. You can't send any message faster than light.

It's very important, because faster than light travel is backwards time travel for some observers. The universe doesn't have that, and if it did, it would fuck up causality.

Really. What motives are you ascribing?
