Brevo dsn installation

Hello, 

I need your support about email delivrability. 
 

I cannot receive email from my website on a gmail adresse. 
 

I decided to install wp smtp on my Wordpress and create a brevo account. 
 

however on my dns I have multiples entries as my Google workspace and my default Squarespace dns. 
 

Do I have to remove all of them before to write the DNS entries provide by brevo?

thank you for your help.
