If the 2019 federal tax return was rejected by the IRS, you do Not amend the 2019 tax return. You correct the error and file the tax return again.
Most e-file rejections by the IRS are for an incorrect prior year AGI. Since a 2019 tax return can no longer be e-filed the 2018 AGI is no longer needed.
