It appears that income reported on this form 1099-R is taxable.
As you have already filed, you have to wait to see if your return is rejected or accepted.
If your return is rejected by the IRS, you can add that 1099-R and correct other errors, then re-file your return.
If your return is accepted, you'll need to amend your return. Please note that the amended form will not be ready before mid-February.
To amend your return, please follow the instructions in this TurboTax Help topic.
