It's no secret that Scarlet Witch is one of the Avengers' most powerful team members. Her chaos magic is so strong that it can even go as far as warping reality itself if Wanda wills it. As powerful as she is though, Marvel writer Jim Zub just confirmed that there is a limit to her incredible powers.
Avengers: No Road Home was a miniseries by the massive creative team of Zub, Mark Waid, Al Ewing, Paco Medina, Sean Izaakse, Marcio Menyz, Erick Arciniega, Jay David Ramos, Carlos Barberi, Juan Vlasco, Jesus Aburtov and Cory Petit. The story involved a team of Avengers fighting against the Greek Goddess Nyx as she threatened to cover the universe in eternal darkness. During the series, the House of Ideas was introduced as the dwelling of the One-Above-All (Marvel's equivalent of God) and the core of all existence.

The idea that she would be connected comes from notes of a retreat Marvel held for the creative staff of the Avengers comics. The note, published as back matter for Avengers: No Road Home details story beats for the series and includes a line that says «Scarlet Witch is the only mortal connected to the House of Ideas.» Zub then clarified in the tweet that the idea was considered but ultimately dropped before the story hit publication.
Wanda is _not_ connected to the House of Ideas at this point. That page of back matter contains notes taken at our story planning meeting. Not all of those concepts made it into our final story.
