"The planet is tidally locked to the star, meaning that one side is always facing the star "

How is the gravity about the same as earths if the planet does not spin, or is the planet spinning at the same rate that it is revolving around it's star, like the moon. So I guess gravity does not just come from the centripetal force. Are there any other forces that contribute to planetary gravity? If not the planetary year should be very small.

Gravitational force is dependent on mass, not how much an object is spinning.

So centripetal force is independent from planetary gravitational force...
