TurboTax error code 606 indicates an invalid license code, often caused by using an online activation code in desktop software (or vice versa), mistyping the 16-character code, or using a version mismatch. To fix this, verify you are using the correct code for the specific software version (desktop vs. online) and re-enter it carefully.

If you are getting Error Code 606, you would need to double check the code you are entering.  Be sure that the O is O and not 0 and that no numbers are inverted.
