Motivation:
1. You have registered a domain on GoDaddy.
However you cannot find a way to create forwarding email address.
2. Reason: Email forwarding credits are no longer included with a domain purchase.

3. A solution: As of early June 2019, GoDaddy discontinued the addition of email forwarding credits to new domain registrations. An Email Forwarding package with 5 addresses is available for purchase at only about $3 a year. They can be purchased by contacting customer support and requesting a Legacy package.
4. You may want to transfer your domain from GoDaddy to NameCheap or Epik who supports creating forwarding email addresses for free.
However you should ensure that your new registered domain is eligible for transfer.
Solution:
1. Domains can be transferred almost any time.
However, ICANN prohibits domain transfers within 60 days of registration or prior transfer.
