I’m trying to fill out a 1099 form from my employer not Self Employed. What do I need to do

If you were paid on a 1099-MISC when you were actually an employee, you should not pay self-employment tax on this income either.  You would pay 1/2 of social security and Medicare tax, and the company you worked for would have to pay the other 1/2.  To claim this would require you to file Form 8919.  

If you believe you should have been treated as an employee and not a contractor, begin the process to file Form 8919 here:

• Federal Taxes
• Wages and Income
• Other Common Income
• Enter 1099-MISC for the time being
• On the next screen, just briefly describe your work (i.e. Sales, landscaping, etc)
• Immediately after the 1099-MISC entry you'll see checkboxes, including "your employer reported on a 1099 but it should have been on a W2"
