How and where do I report a return of excess for my Traditional IRA contributions in 2024 on my 2024 tax return?

I was self-employed in 2024 but also had some income from prior employer. I contributed 8K to my traditional IRA in 2024 but now discover that I am not eligible to contribute anything (last paycheck included one final contribution to employer plan.) I completed a return of excess form with Fidelity but do not see where I am supposed to document this in my 2024 tax return. How and where do I do this?
