It has added my state returns into my federal returns and now is making me pay!!! This is the second time I'm going through this. Please advise!!!

I am at the end of my filing and now it's saying I owe 30 dollars. I hate this. This is the second time this is happened. Your systems are deceptive and are misleading the consumer to pay for your products. Please advise on how to delete the state tax return as a part of the filing.
