My wife did not work last year, it was child care the previous year are we required to still fill out the self employed forms on the taxes?

No. You can get rid of that form. 

Don't delete your business if it closed sometime in 2020. Instead, report the business and make sure you select I stopped [your business] in 2020 on the Tell us about how long you've worked in [your business] screen.

Otherwise, follow these instructions to delete a business that transferred over from your 2019 return but is no longer owned by you as of January 1, 2020.

Instructions

1. With your return open, search for business (schedule c). Be sure to include the parentheses.
2. Select the Jump to link in the search results.
3. On the Your 2020 self-employed work summary screen, select the trash can icon next to the defunct business.
4. Answer Yes, delete this info to confirm the removal of all business-related forms.
