That depends on how you filed in 2021, 2022, 2023 and 2024. I assume you did not remove the excess. Did you include form 5329 in each of those years and pay penalties? Did you include form 8606 in 2021 to track the non-deductible basis?
Also, let's clarify what you mean by "Excess". In 2021, you could contribute up to $6000 to any IRA, or $7000 if you were over age 50, or up to the amount of your compensation from working (wages or self-employment income). You can contribute that amount no matter what your other income and tax situations are. You might not be allowed to contribute to a Roth IRA, and you might not be allowed to take a tax deduction, but you can always contribute $6000 (or $7000). And the IRA broker should not allow you to contribute more than that amount, unless you have more than one IRA account at different brokers.
So to start, what do you really mean by "excess"?
Did you include form 8606 with your 2021 return?
Did you make any additional non-deductible contributions in following years, and if so, did you include form 8606 to update your basis?
Did you include form 5329 on your 2021 and every following year tax return?
