Although you can add buttons and things to move to the new record, it is important to understand that none of this is necessary.
just create a (bound) form based on one of your tables with the form creation wizard
at the bottom you will see navigation buttons. click the last button with the star - this will rtake you to a new record. If you want to find an existing record - click in any data field - name, address, phone number - anything. Then click the binoculars icon, and enter what you are looking for.
Simple

Everything else you do modifies this basic behaviour, or maybe make this stuff slightly more accessible - but it is important to understand that this behaviour is at the centre of pretty well everything access does.
So You do not normally need a button to clear a record, or a text box to find a record
and in fact creating a text box, to navigate to a record is relatively advanced stuff
So the best thing is really to read through a general access primer, to get an understanding of access tables/forms/queries as a start.
