Roth IRA Deposit Recorded in Wrong Year

My son contributed to a Roth for 2019 but didn't specify the year on the deposit and it was applied to 2020. Too late to fix it now.   Looks like the Roth contribution wasn't reported to the IRS and is only shown in TurboTax on the IRA worksheet. It has no tax impact since it was an after tax contribution. Is there anything I need to correct or can I just add the 2019 amount to the 2020 balance this year to bring the historical basis up to date ?

 

Thanks
