SPF entries in my domain DNS are not right

I just received the following messages and can you please tell me what I'm doing wrong.

SPF entries in your domains DNS are not configured to match with Zoho.Please configure SPF to ensure better email delivery.

Dear admin of smartenglishprofessionals.com, 

You are receiving the alert, as the domain smartenglishprofessionals.com added in Zoho for email hosting, has some of the records not pointing to Zoho, even though the domain is still hosted with Zoho. 

As an implication, the users may intermittently face issues when sending/ receiving emails in Zoho Mail. We request you to have only the Zoho recommended MX records to receive emails in Zoho without any delivery problems. 

The current MX records with the priority are:

10 mx.zoho.com. 216.52.72.121
10 smtp-fwd.wordpress.com. 192.0.97.133


The valid MX records to receive emails in Zoho Mail are
Priority MX Records
