Hello Teresa Wasnock
Thank you for posting question to Microsoft Q&A Forum.
May I know if you've followed the instruction given by Q&A Assist? Especially the second one?
Please follow this article: https://support.microsoft.com/en-us/office/uninstall-skype-for-business-28c4a036-7f22-406c-b7f4-87894cbaf902 at the second part.
It could be possible that your Skype for Business is integrated with the other Office apps - you might need to uninstall the Office Suite. I do not recommend this part if you are already having the licensed version Office apps within your computer. The first part of the given article above should be my suggestion in case you would like to have this application not automatically opening when turning on your computer.
Please share with me your update once you check my suggestions.
