You do not do anything about that for your 2024 tax return. You gave a W-4 to your employer to tell the employer how much tax to withhold from your paychecks. The employer used that information; it did not go to the IRS. The W-4 you gave the employer does not dictate how you have to file your tax return. Just enter your dependent in MY INFO to claim the dependent, and enter your W-2 as it appears.
If you want to change the amount that is being withheld from your paychecks you can prepare a new W-4 to give to your employer.
