I understand that you are using Apple's Messages app to send and receive text messages. Is that correct?
Short answer: All text messages are sent through your iPhone.
First confirm that you are able to send and receive those text messages using your iPhone: Send and receive text messages on iPhone - Apple Support. If that is not working for you, read If you can't send or receive messages on your iPhone, iPad, or iPod - Apple Support.
Then, configure your iPhone to "forward" those text messages to your Mac: How to forward SMS/MMS text messages from your iPhone to your iPad, iPod touch or Mac - Apple Support.
