Timeline E, Timeline A: 2026

After sealing a tear in the barriers between realities, SABER Agent Monica Rambeau finds herself in the reality of Timeline A, where she is recovered by the cosmic superhero Binary (the alter ego of her mother, Maria, who in this reality did not have a daughter) and the X-Men’s Hank McCoy. (The Marvels)
Side note, again: the vast majority of MCU projects post-Avengers: Endgame are no longer contemporary with our own time thanks to the five-year jump between it and Infinity War. Not accounting for any kind of time differential traveling between realities, we’re making the assumption that as The Marvels is set some time in 2026, Monica lands in the equivalent year in the reality of the first three Fox X-Men films.
