Even though it is now past April 17th 2024, you can still take the contribution back if you filed yiour tax return on time. IRS calls it timely filed.
If you have to amend because allocable earnings are greater than zero and/or you took a deduction, write "Filed pursuant to section 301.9100-2" on top of 2023 Form 1040-X
You already have the relevant paragraph in bold above.,
