Not sure what stimulus checks you are referring to. You have not told us what state you are in so we do not know if there was a check you should have received in your state. As for federal stimulus checks, there is no federal stimulus check for 2023 and nowhere on a 2023 tax return to enter anything about a stimulus check. The federal stimulus checks were issued for tax years 2020 and 2021.
Please explain what you are trying to do.
