I don't understand what you mean by "the 1099int portion" and "the seller financed area." All interest income goes in the first section of Part I of Schedule B, both from a seller-financed mortgage and from a 1099-INT. The seller-financed mortgage is supposed to be listed first, and TurboTax does that. It did it the same way last year.
Are you sure you're entering the interest income correctly? There are separate topics for interest on a 1099-INT and interest from a seller-financed mortgage.
I also don't understand what you mean by "the 1098 information." You get Form 1098 for interest that you pay to a mortgage lender, not for interest income that you receive. And you don't issue a Form 1098 for a seller-financed mortgage. You should not be entering a 1098 for your interest income from a seller-financed mortgage.
