My spouse is (the only) W2 employee (non-owner, part-time) in my sole proprietorship business. Where in TurboTax do I add my spouse's elective contribution to my solo / individual 401(k) (and the businesses corresponding profit sharing contribution). If I enter her contribution manually it requests that I withdraw the contribution. My understanding is that she is uniquely eligible to participate in my solo 401(k) being my spouse... elective up to 18K of income + profit sharing of 25% of her salary.
