Congratulations on paying off your mortgage. To eliminate TurboTax questions about mortgage interest , you will have to delete
any Home Mortgage Interest Worksheets or Form 1098:Mortgage Interest Statements
that carried over from your 2016 tax file.
See: How
do I delete forms in TurboTax Online?
After deleting these worksheets and statements, log out of the
program. When you log back in, use the Delete a Form tool (List of Forms
in My Return) to confirm these worksheets and statements have been removed
from your return.
