remapping or Parse error_is this fixable in my environment? Importing open zeppelin contracts fails

Question

When I set import to "@openzeppelin/contracts/etc/etc" VS Code immediately shows not found. File import call back not supported but running truffle compile shows what I think looks better (considering the output). When I change the import to "node_modules/@openzeppelin/contracts/etc/etc" VS code likes it but truffle compile output now A) shows WAY more contracts, B) hits me with errors like "this function; this var; has already been delcared". It shows the error in live in my files and points to the relevant imported source contract as the first to declare. I can't get truffle solc-js compiler to understand that these are separate contracts and it is a reference... It's like both the imported and my contracts are in the same folder or something. (but are not).

I have changed the names of literally everything (I think) except for my CrowSale sol file name. I just can't figure out which combination of attempts is the right one or maybe it is a config setting and not a naming or syntax issue.

Questions

Why are the contents of imported contracts like ERC20.sol creating a declaration error based on the contents of my contracts. Where are/is my error(s) in the A) File Name B) import call C) contract declaration D) or in deployment artifacts require(a file) naming scheme?
