If you use TurboTax Online, you have to log in to your account, choose the return and, from 2024 tax return (on left menu), you can review each section of your and wife's return. For the split income optimizer, you just have to click on Review // Revisit // the optimizer will start and then, if you want to change the amount, click on I want to change my split, and follow the steps on the screen.
Thank you for choosing TurboTax.
