Answered by Ustaadha Bint Salih.
During the sitting position in salah (ie when reading attahiyyat) do women sit on their left foot?
During the sitting of tashuud, women are ordered to take out both their legs and sit on their bottoms.
(Jamme-Masaneed p.400 v.3)
In response to your question, in the sitting position of salah, women do not sit on their left foot, but rather on their bottom.
Only Allah knows best.
