For a Walmart seller account, you must select an entity type that matches your IRS records, I have a single member LLC and not sure what entity type i should be using for tax purposes. My LLC sell on Amazon Seller Central but never ask for the entity types that Walmart is asking for. So im trying to be consistent by using the same entity type to avoid IRS issues. Below are the Walmart entity type options. The only one that somewhat made sense for me is the LLC- S- Corp. However, i dont have that setup in amazon like i mentioned cause it just went off the LLC itself information.
LLC S-Corp
LLC - C- Corp
Partnership
S-Corporation
C-Corporation
