You will need to amend your return using Form 1040-X, and include the income from the 1099-NEC. You are not able to amend the 2021 tax return yet since Form 1040-X is not available from the IRS. It is expected to be available around the middle of March.
When the form is accessible, you can input the new information in the 1040-X, amended return, and e-file the return. Here is a TurboTax help article about amending your return.
