Yes, form 1099-misc box 7 "nonemployee compensation" is treated as being self-employed for taxes. You can spot this coming when there's no taxes being withheld from your paycheck. Your position should have some autonomy and independence of skill to qualify as self-employed. While you pay self-employment taxes, you also get to deduct all of your expenses. If you don't have any expenses, then you may not really be self-employed.
If it's not correct; meaning you truly are an employee, then you can file Form SS-8 Worker Determination and challenge your employers categorization. Instructions at IRS for qualifying for and completing the form, here:
