Do I need to do an amended 1040x if the only thing that needs amending is Form 8606? I just made a non-deductible trad IRA contribution for 2019 but already filed.

It's very confusing what exactly is required of me to do. The only thing that needs to be amended is the 8606. Nothing else about my 1040 or tax liability/refund will change. If I do need to go through an amendment process, is the 1040x what I need to complete on TurboTax? First time ever dealing with a tax amendment so I feel a little helpless. Thx!
