Email record wizard not working as intended?

Hi, new to the community and any tips appreciated thanks in advance.

Having problems with sending emails to gmail and been advised to add a TXT record to the email security section - “v=spf1 ~all” but the wizard does not create a field to type in this and add additional text fields -

All i get is a repeat of the general TXT rule cloudflare added?? Any help appreciated thanks
