I am trying to draw a circle of a specific size whose circumference travels through 2 defined points. The only thing I have found is a circle whose circumference travels through 2 points and the diameter is determined by the distance between the points.

I often do it the old-fashioned way. Because I forget all the myriad of Tools that TurboCAD has.

I:

>Insert 2 Construction Circles, initially snapping their center-points at what you termed "[the] 2 defined points". Those Construction Circles having the radius of what I want my eventual "specific size" Circle to be.

>Insert the desired Circle, Intersection_Snapping its center--point to the intersection of those two Construction Circles; then Center-Snapping to one of those Construction Circles.

Note: The above does not necessarily result in tangency; you did not specify that tangency was a requirement.
