TurboTax has reported interest income received without a 1099-INT in two places so it's taxed twice. How should this be done to avoid the problem?

I received interest income without 1099-INT. I added it as Miscellaneous Income with a description "Personal Loan Interest". Turbotax included that amount with the interest reported on 1099-INT (not a problem) but also included the total on Schedule 1, Line 21. This results in that income being taxed twice. How should this interest be reported to avoid this?
