Regarding Aniken Skywalker

I read briefly some where is it true that Darth Plagieas and Sidious created Aniken via creating his mother and manipulated the midiclorians in her womb to create aniken etc ? Is this true with regards to canon?

No.

Originally, it seemed like Soule's intent was for Palpatine to have created Anakin, but that is no longer the case(as both Soule and Martin confirmed on Twitter):

Anakin's origins in canon are entirely unknown.
