State tax filing

Since you seem to know what you're doing, may I ask another question? My taxes owed (Federal) increased when I contributed more to my SEP-IRA. It may or may not have to do with the affordable care act health insurance but I can't figure it out; also it asked how much of the contribution is attributed to my ecommerce business, and I don't know what the correct answer to that question is. Thank you for your time.
