What is the business code for mobile app development on Schedule C?

[manbeing]

I can only find code 541510 using 'Code lookup' in turbotax, but I really don't think 541510 is a valid NAICS code (it even doesn't list on NAICS official website)

Will 511210 (software publisher) work for mobile app development? but i cannot find this code in the TT

'Code lookup'

See https://www.irs.gov/instructions/i1040sc#idm140624746033120

The codes changed recently so use the most current one that is applicable.

The business code on Schedule C is not a NAICS code. You have to select a code from the list in the IRS instructions for Schedule C, which tagteam gave you a link to. The IRS list is "based on" NAICS, but it is not the same as NAICS.
