Form 1099 NEC

I am another Amazon Vine participant. I understood from the beginning that I would be taxed on items received - mostly at msrp. I have entered my information from the 1099 NEC & have completed all my entries for the return. At the final review, errors are shown - all regarding the Schedule C generated from the 1099NEC entry. It is asking for a 6 digit Principal Business activity code - I don't have a business & have no code. It is asking me to return to the form & complete the topic as to whether it is a qualified or non-qualified business. Is this question meant for the business I don't have or asking if Amazon is qualified or not? It is also asking for a business address - for me or Amazon. There is an option to check a box stating that the business name & taxpayer name are the same. I assume I should check this even though there is no business name. Schedule C non cash accounting method must be entered - don't know what to enter form cash, accrual or other (assuming other). Material boxes must be entered - line G - yes or no? I know that the 1099 was required. Is it ok to enter the income information & ignore the schedule C so that the amount of tax will be entered into the final total?

I am having to mail in this return due to a form 5329 being required for a financial institution that failed to make a requested RMD. I did not catch the mistake until April 11 - 10 days after my deadline of April 1 due to being my first RMD. I have a feeling that the return may already catch some extra scrutiny. I do not see a way to file online with that form & Turbo Tax. I appreciate any help that can be provided.
