Does any of the turbo tax software include creating 1098-int forms?

I assume you mean a 1098 for a mortgage? If not, comment back here.

You do not need to send a form 1098 if you are the owner financing a home. You would only file a Form 1098 if you are in the business of providing mortgage financing (mortgage lender or bank).

You would need to provide your buyer with your social security number or an employer identification number (EIN) so that they can claim a mortgage interest deduction within their tax return. 

So, if I am the owner, lending the money to the buyer, I don't have to prepare a 1098, even if I collect more than $600 in interest in a year?

II have 4 properties financed and have been filing 1098's for several years
