If you have already filed your return and it has already been Accepted, you will need to wait until the IRS fully processes your return and you receive your refund.
Next, you will need to Amend your Tax Return by filing Form 1040-X to include the Form 1099-R.

NOT make any changes on your return in TurboTax until this form
