Yes. The early withdrawal penalty is an adjustment to income so it will reduce your gross income which reduces your adjusted gross income. When you enter your 1099 INT into Turbo Tax, the early withdrawal penalty will automatically be reported as an adjustment to income on your Form 1040.

what is the tax treatment for a cd penalty that was assessed in a prior year (e.g. 2021) and then identified as an error in 2024? are corrected 1099's required or do we issue a 1099 INT for the year the money was refunded?
Usually, banks or financial institutions where your CD was held would issue the 1099-INT form so not sure why you as a customer would issue a 1099-INT. I'd recommend contacting the financial institution or bank where the CD was held to find out whether they would be planning to issue a corrected 1099-INT for the tax year where the penalty was initially assessed or if they will issue a 1099-INT for the year when the penalty was reversed.
Since tax returns are typically prepared on the cash basis, it would make sense that they would issue a 1099-INT for the year of repayment, but verifying with the bank is your best way to confirm.
