I know turbo tax is saying I owe way more then I do but I can't figure out where the mistake is. I am self employed and my husband is W-2.

There is no mistake , self employed pay SE tax of 15% on top of income tax.

I have been self employed for 6 years I knew it was wrong. I just figured out it had my income in twice. That makes a huge difference!!! Thanks. Unfortunately I still owe but not a number that will give me a heart attack!
