Hi NicolleLeney,
Thank you for reaching Microsoft Community.
Was the box for the typecover still sealed when you received it?
Have you tried cleaning the typecover? See: Clean and care for your Surface (microsoft.com) for tips.
I'm not sure what should be the smell of the typecover out of the box but you may contact our online Microsoft Store support for further assistance and for options available in case you need to have it replaced due to the strong smell. See: Contact Microsoft Store Support.
We also welcome our other Community members who may have a similar experience to share here.
