i need formula for Due date, and days overdue using EXCEL

The following is a list of people who have borrowed books from the library. There is a column for check-out date and a column for due-date. In the 3rd column, please calculate days overdue. If a book is NOT overdue, this column should reflect the number zero. Books are checked out for a total of 14 days. Calculate the due date based on the check-out date. Place it in the due-date column. If the book is overdue, this column should reflect a positive number which is the days overdue as of 1/28/2020 In the "Alert" column, place the word "overdue" if the person's book is overdue. Format the Headers and Underline them so they will not be confused with the data.
