Deductions & credits
You can enter more than one Form 1098 in TurboTax if you have more than one loan on your home. However, you can only deduct interest on loans that are secured by your personal residence.
If the second property is adjacent to your home but not secured by your home, then you would not be able to deduct the interest. If you were to, for example, build an addition to your home that secured the loan, then the interest could be deductible.
See this TurboTax tips article for more information about deductible mortgage interest.
See this help article for information on entering Form 1098.
