Were do i enter my entertainment expenses?

For what?  Are you filling out Schedule C for self employment?  You can enter 1099NEC or cash Self Employment Income into Online Deluxe  but if you have any expenses you will have to upgrade to the Premium version.

Are you entertaining clients for business?  What "entertainment" expenses are you trying to enter?   You are posting from online Deluxe---which does not support preparing a Schedule C for business expenses.  If you need to prepare a Schedule C for business expenses because you are self-employed, you need to upgrade to Premium software.
