Level 2

As stated in this help article, which was recently updated:

You may receive a message like:
ZIP code is invalid for Electronic Filing. You must enter a valid ZIP code for your state. Enter a correct ZIP code in this format 'nnnnn' or 'nnnnn-nnnn'
TurboTax follows the IRS guidelines for acceptable ZIP codes. If the two-letter state abbreviation doesn't match the ZIP code, you'll receive this error when attempting to e-file.

Solution

If you receive the error mentioned above:

Double-check you entered the correct two-letter state code
Make sure you've entered the ZIP code in either 5-digit or 9-digit format (for example 12345 or 12345-6789)
Look up the correct ZIP code for the street address in question
