No, she doesn't. Sharingan is what devolved from Rinnegan, she can't have Sharingan since it became a thing with Indra (possibly Hagoromo). Kaguya has the Shinju's eye which is a Rinnegan. The Shinju hadn't had a Sharingan and taken Hashirama's cells to upgrade it. Get this into your head and all will be ok.
