I was able to do this by working it backward from form 8881. Create and open 8881 up in the "forms" section. Up top on the form it has a box that links to Sched C, F or form 4835 depending on what type of business you operate. I clicked on the Sched C box (sole proprietor) and then hit QuickZoom to go to that form. There I was able to enter my startup costs, as well as claim a $500 credit for creating a 401k with a automatic enrollment option with the plan. It places the qualified startup costs automatically into the business expense form.
Note that Turbotax program the finalized 8881 will not be available for e-filing until 3/6/2024
