Sorry but a 1099NEC is for self employment income. Why did you get the 1099NEC?
Yes you are the owner of your own self employment business. You are in business for yourself. Use your own info. The people or company that pays you is your customer or client. You need to fill out schedule C for self employment business income. You are considered to have your own business for it. YOU are the business.
When you are self employed you are in business for yourself and the person or company that pays you is your customer or client.
If you have expenses you need to upgrade to the Self Employed version. You need to pay self employment tax on it.
Self Employment tax (Scheduled SE) is automatically generated if a person has $400 or more of net profit from self-employment. You pay 15.3% SE tax on 92.35% of your Net Profit greater than $400. The 15.3% self employed SE Tax is to pay both the employer part and employee part of Social Security and Medicare. So you get social security credit for it when you retire. You do get to take off the 50% ER portion of the SE tax as an adjustment on 1040. The SE tax is already included in your tax due or reduced your refund. The SE tax is in addition to your regular income tax on the net profit.
