I tried to add a SEP IRA contribution (that I have not yet made) to my filing, and it lowered my refund due to cancelling out my Traditional IRA deduction. I want to remove this from my taxes as I have yet to open the SEP IRA and make any contribution to it. I thought is may be a way to maximize my refund, as I had a small amount of 1099-MISC income. My Traditional IRA was the only retirement plan contribution of any kind for me in 2016.
