1) You could have obtained a return of the contribution had you done so by the October 15, 2024 deadline for doing so. Of course you are now beyond that deadline, so you are stuck with the nondeductible contribution.
2) There is no penalty on having made a nondeductible traditional IRA contribution provided that you had sufficient compensation to support the contribution.
3) You'll need to track your basis in nondeductible traditional IRA contributions and track it for pro rata application to traditional IRA distributions until you no longer have any funds in traditional IRAs. This is done on Form 8606 Part I which must be filed any year that you make a traditional IRA contribution or distribution that changes your basis in nondeductible traditional IRA contributions.
