Deductions & credits

Hello  - For 2021, I have contributed excess of 6k for my Roth IRA and excess of 6k to my wife's traditional IRA. I filed our 2021 return and completed form 8606 declaring excess nondeductible contribution for my wife's traditional IRA, however forgot to disclose roth IRA excess contribution? 

 

What actions I need to take to correct my filed 2021 tax return?  What are my options. Can you please provide detailed steps? 

 

Also, when should I withdraw the excess contributions by? What forms I need to obtain?
