Hey Jack, Sorry for the lack of detail in my question. crazy long day!
It's a single member S Corp, It used to be an LLC 5 years ago(I'm familiar with the 60 months limitation rules)
I do understand the difference between the 4 types of corporate structure. i'm in first year doing taxes and bookkeeping, so i'm not deeply submerged in the different forms and implementations.
Again, I apologize for not being clear enough and truly appreciate everyone's time.
