IRS PUB 550 also makes it clear
Reporting options for cash method taxpayers. If you use the cash method of reporting income, you can report the interest on Series EE, Series E, and Series I bonds in either of the following ways.
1. Postpone reporting the interest until the earlier of the year you cash or dispose of the bonds or the year in which they mature.
@Gina1212 If the bonds reached maturity in 2023 that's the year to report the interest.
as for 2024 1099-INT in the adjustment section check the box other and enter the interest as a positive number.
