Hi there, Kim.
We have a guide article that talks about setting up S-Corp Medical health premiums in QuickBooks Desktop. You might also need to manually change the amount every time the company pays for the premium. Here's the link: https://community.intuit.com/articles/1762809.
With regards to deleting the YTD entry, please refer to the steps provided on the other question you submitted. Let me link you to this thread: https://quickbooks.intuit.com/community/Employees-and-payroll/YTD-Payroll-Entry/m-p/216114.
Feel free to visit us again in the Community if you have follow-up questions.
