Normally Cloudflare automatically synchronizes all of the records, sometimes we may need to manually change “A” Record from Cloudflare DNS.
Login to your Cloudflare account and then select your domain.
Click DNS, look in the down, you will find all of the DNS zones here. You need to update only one “A” record to resolve your website, record for your domain only. But you can update others' records if you need.
If google.com is your domain name, You will need to change the IP address from the line. You can contact your hosting provider if you don't know it.
