Just e-tax or 個人業主?

So I went to the tax office… and one employee just told me it was 非課税. Save invoices and do e-tax. I should get WHT back. Then another came over and gave me a form for 個人業主. From my research I think e-tax is correct…. But then the other person said 個人業主 so now I am confused…

So here I am asking Reddit for tax advice…
