its telling me my box d control number is wrong

Leave box d blank (empty) it is not required to e-file a tax return.

If the error persists then delete the W-2 and re-enter manually to clear the error.

If TurboTax is telling you that your Box D control number is wrong, try  leaving it blank. If this does not work, try entering a number like 12345 67890 (5 digits, space, 5 digits). This Control Number is for employer payroll systems and it is not required by the IRS. so this will not affect your tax return.

If this does not work and you imported your Form W-2 try deleting it and re-entering it.
