TurboTax can claim there is a "zip code" error, even if it's actually something else wrong with the address. So the zip code may not be the issue.
First, be sure you are using the correct state abbreviation. Iowa is IA, but ID, IN, or IL can easily be mistakenly selected in a dropdown menu if the mouse accidentally rolls.
Use the USPS lookup tool to get the official address styling and zip code:

If the street address has punctuation, try using no punctuation. e.g., 123 N St Marys Ave instead of 123 N. St. Mary's Ave.
