How do I find the industry code for marketing within TurboTax? For 2018 returns, it appears that you have to use the industry codes from your tax preparation software.

Here's a link to the most current version of the NAICS that works in TurboTax. In a search for "Marketing" this number came up - 541910. This may not be what you are looking for, but you should be able to find something suitable here. (hint, click on the "all examples" for a detailed list).

Thanks Kim. This worked!
