My Pennsylvania tax return is asking about information for a business i own but i have no business. How i do enter that i don’t own a business?

You might have accidentally checked a "box" early on in the information section that is prompting this. Try saving the return and exit out of the program then log back in and revisit the wages and income section to make sure nothing pertaining to having self employment income is mistakenly checked off. If it is, you can just easily delete it. It might take a few minutes, but it will resolve this issue you are encountering. Just be sure to follow the steps and when you get to the screen where it asks you if you have any other self employment income information and it shows this "business" listed, click on the little trash box to the far right of this "business" and confirm that you would like to delete/remove this item from your return.
