State tax filing

I can see the 1040 but our info says filing jointly. I'm over 65 but my wife is not. We are not taking the standard deduction, but itemized. We have 2 W2's, a 1099INT, 1099DIV,1099R, stock sales, an my SSN income. It has us owing over $7,734 to Fed and $589 to MN state. It has our tax liability at over $15K on taxable income of just under %79K. This can't be right based on our last years return and what we figured out from doing both Fed and state tax in long hand.
