LLC and 1040C

[Julio Bradley]

I recently moved one of my rental properties into an LLC to protect my personal assets. When I filed my taxes, my tax agent said that I must file a 1040C for the LLC and that the 1040C does not protect my personal assets. They told me that I must move the property into an S-Corp in order to shield personal assets. Any guidance or tax laws for this? Any questions I Can ask the agent for further explanation or rebuttal? Thanks for any input
