If you want to delete the startup costs:
Old thread, but I ran into the same issue. Hopefully this helps someone in the future:
The answer didn't help me since startup costs weren't listed in my EXPENSES section. The form is also absent under Tax Tools. However, I was able to resolve the issue by adding startup costs THEN subsequently removing them. Upon continuing with my return and reviewing, I was no longer prompted for this form.
