Addresses are usually long and manually typing increases the chance of typographical error. You can turn on the auto suggestion of the address to prevent this to happen and to help your users to easily encode their addresses. To set this up, you need to go to:
Form Fields
Click on a single text field where you intend to store the address
Advanced section
Turn on the Enable address autocomplete toggle.
As users enter text in the field, a list of addresses will dynamically appear in the form where the users can choose from.
