In April 2023 this is still an issue. I have no edit button for the business code. I was trying to enter 458310. I copied the exact name of the NAIC description (Jewelry retailers) into the work description field and it still shows the default business code of 999000. I cleared all cookies and cache. I talked to the TurboTax representative, who suggested I try incognito mode in Chrome. None of these worked. I was getting an error for the federal return, with the only option to print the return and file via snail mail. You can bypass the step at the end of the filing process of checking over the return and simply file it. I did that and it worked.
