primary residence tax ememption, sold in LLC

[Doug Williams]

Curious if anyone has tax advice if a primary residence was lived in for 4 years, converted to a rental and placed in LLC for a year, then sold. Is the gain subject tax or can it fall under 2 of the last 5 year rules for primary residence? I feel like I may have received some bad advice and now curious if I can claim the primary residence at least for a prorated amount of the gain...
