to summarize the path forward:
amend your 2023 return by submitting 2023 Form 8606 (see above)
Line 1 6,500
Line 2 18,000
Line 3 24,500
Line 14 24,500
The assumption here is that no deduction was ever taken for any of these Traditional IRA contributions.
The submitted 2023 Form 8606 becomes your most recently filed Form when preparing 2024 tax return.
You didn't say if you are making a non-deductible contribution for 2024.
If no, 2024 Form 8606 is not needed.

irrelevant if you know the prior years basis needs correction.
