When helm encounters parse errors while processing multiple YAML documents in a single file (like your case) the error message can be a bit misleading. Although it says line 20, that point is in reference to the beginning of one of the YAML documents in the file, not the beginning of the file itself. With most parse errors, you should check the line it mentions as well as the previous line for issues. In your case, it looks like Line 19 of the StatefulSet document on the command line would cause it.
