How do I know if my installment sale of my home qualified for a Section 121 exclusion?
Home Sold in 2024
Your 2024 Section 121 exclusion is found on your 2024 Form 6252, Line 15.
Home Sold in Another Year
Your prior year Section 121 exclusion is found on Form 6252, Line 15 for most prior years. To be sure, look for a description that says "enter the amount of your excluded gain".
