How to declare 401K excess contribution amount withdrawal made before April filing date?

I realized an excess 401K contribution was made in 2024 and withdrew the money in March 2025. How ever, the 1099-R will be issued in 2026. What are the steps for me to add this in my 2024 tax filing and avoid any penalty? Does turbotax assess the taxes for the withdrawal amount? Pls advise.
