Configuring SPF for Godaddy Hosting

Configuring SPF for Godaddy Hosting

I get an alert message saying to update SPF and DKIM.  I do not want to accidentally disrupt our email by inputting the wrong settings.

I checked the current Godaddy settings and it has two TXT records:
         TXT record:  Host: @ 

 TXT value: v=spf1 a mx ptr include:secureserver.net ~all

 TTL : 1 hour

and

        2nd TXT record

TXT - Host: admin

TXT value: v=spf1 a mx ptr include:secureserver.net ~all

TTL: 1 hour


According to the Zoho help file, it says to update to: 

  1. In the Host field, specify @. 
  2. In the TXT Value field, enter v=spf1 include:zoho.com ~all
I have also seen somewhere it mentioned to do  v=spf1 mx include:zoho.com ~all  

What would happen if I just replaced "secureserver.net" with "zoho.com" in the existing TXT record?  Would it be better to do v=spf1 mx include:zoho.com ~all  or not to include the "mx"  

Will I cause major disruption if I get this wrong?

Also what about the second TXT record that I saw listed on my DNS manager:

2nd TXT record

TXT - Host: admin

TXT value: v=spf1 a mx ptr include:secureserver.net ~all

TTL: 1 hour


?

Is that second TXT record something that needs to be removed? or changed?


I am grateful if anyone knowledgeable on this can give me some info and reassurance before I make these changes.
