An inheritance is not taxable income to the recipient of the bequest. In some states, an inheritance is taxed to the estate itself. One the inheritance is invested at a bank or brokerage account, any earnings - interest, dividends, etc. - are taxable just like any other interest or dividends. Just enter the interest in a separate screen, using the name and Fed EIN of the payer of the interest. You may have gotten a 1099-INT if the amount of the interest income is greater than the threshold for filing a 1099. (The whole amount of interest income received in 2022 is taxable even if no 1099-INT was received.)
