I sold a home on land contract how do I issue the tenant a 1099 int form for the interest he’s paid me?

Unless you are in the business of lending money you do NOT need to issue a 1099.  What you both should have is an amortization worksheet showing how much of each payment is interest and an annual total.  You also need their name, address and SS# or EIN for your Sch B  and they need your info for their Sch A if this was a personal residence  or a Sch C if this was a business property.
