Unless you are in the business of being an executor (which is highly unlikely), the income is reported as Other income on Line 8 of Schedule 1 which, in turn, will wind up on Line 7a of your Form 1040.
In TurboTax, click the Start button to the right of Miscellaneous Income, 1099-A, 1099-C and then click the Start button to the right of Other reportable income.
