I'm slightly reconsidering my response above. Let's take one stab at figuring out the problem before you go to a tax professional. But you have to provide more details.
What did the IRS letter say was wrong on your 2023 tax return?
What did the IRS letter say was wrong on your 2024 tax return?
Is it the same error (not necessarily the same amount) for both years?
Was there any significant change in your income or tax situation from 2022 to 2023, such as a different type of income or a new deduction?
Please be as specific as possible and give all the details. If possible, quote the part of the IRS letter that says what was wrong. (But don't post any personal information. This is a public web site.) Keep in mind that we can't see your tax returns or the IRS letters. We don't know anything about you or your tax situation except what you post here.
