You may have to [https://pcsupport.lenovo.com/au/en/products/laptops-and-netbooks/100-series/120s-14iap|enter the serial number] and find out the specifications for your exact motherboard variant. (see Item #4 p.73 of the hardware manual) as some that I searched for had either 32GB eMMC or 64GB eMMC flash storage hard mounted and therefore maybe there is no M.2 slot provided.
