How to wrape a pipe around a 90 degree corner at a slight angle

I have something that seems like it should be so simple and yet I can't quite figure it out.
I have a pipe of known dimenions that needs to turn a 90deg corner (a vertical square tube). If the pipe was perpendicular to the thing it is bending around, this would be easy - just turn it 90deg.
However, the pipe is at a modest incline - about 15deg or so. I can't for the life of me figure out how to model this. I know the bend in the pipe should be less than 90deg.
I am simply trying to draw a line that I can then run a sweep operation on.
You can see a simple starting attempt at this at https://cad.onshape.com/documents/4a8e1cf7dfd5415a2f1c82da/w/324a72f7940143575247ab44/e/83f39bdba508d1efa1a4fe9d
It has three sketches and one part.
The part represents the square tube that I need to bend around
The first sketch "projection" is what the pipe should look like from a top view - a simple 90deg turn.
The second sketch "incline" shows the incoming path that I need to connect to.
The third sketch is empty, where I want to draw the continued line from incline, but I have been unsuccessful in figuring this out.

One option:

May the two straight tubes be in a common (inclined) plane? Then just create the plane and model the tubes and corner in that plane.

The advantage here is you can use off the shelf 90° fittings to make the railing.
Have you tried the "Routing curve" feature?
This has already been answered 3 times now, but I'll throw a full pipe routing workflow in here that I like to use:
Routing Curve+ allows you to measure up to entities, set bend radius, and generate pipes. It even has an integration with Assembly Imposters in case you want to use the assembly BOM with managed parts.
