How to i figure out who brought in what money? We do not share our refund... How do i see what's mine and my refunds and what his is so we can split the refund?

If you are not sharing the refund, you should not share the  tax return by filing "Joint". Try redoing your return in Turbotax as separate individuals, to yield separate refunds. If the two refunds don't equal the total refund on your Joint return, calculate the percentages. Add the two individual refunds. Divide the total by your refund. If the result is 50%, apply that math to the joint refund; 50%.  If your individual return yields a refund that  is 65% of the sum of the two, then you should get 65% of the joint refund.
