You might have added the actual Service Orders entry screen (FS300100) to your dashboard, which will take you directly to the entry form.

Instead, add the Generic Inquiry used to list all Service Orders, that is also linked to the Entry Screen, and has Enable New Record Creation ticked.

That should give you the option to open the list, or click + to go straight to the form.
(The GI is likely this one: FS3001PL)
