the business code on a quick NAICS search
The IRS does not want the NAICS code. They want the Principal Business Code, which is in the Instructions. Although those codes are based on NAICS, the are more broad. Find and use the code in the Instructions that is closest (looking up the NAICS code can give you the first three digits, which will help you narrow down which IRS code to use).
