It should show up as part of the slice. There are a lot of settings in support and one of them is "Touching Build Plate" or "Everywhere". If you use Normal support on that model it will build a rectangular support structure BUT if that base is part of the model (and it appears to be) then if you have the supports set to "Touching Build Plate" then the support structure wouldn't be built because it would need to grow from the top of the base. In that case, switching to Tree supports (which grow at angles) might fix the problem.
Just keep playing with the settings. Things line "X/Y distance" and the "Z distance" and the "X/Y overrides Z" option make a difference when the supports need to grow next to a sloped surface.
Supports can be tough to remove and usually leave scars when the support material is the same as the print material. PLA doesn't stick to PETG very well and so PETG could be used for the support and it will break away easier. There is also water soluble support material available. With my single extruder printer I'm stuck building support with the same material as the print. A set of Exacto knifes and a set of small pics (or dental tools) along with a micro-file set and a pair of needle nose pliers can really help.

That are overhangs, which means they will need support material to print well, or they will sag a bit while printing if you switch off support. Has nothing to do with X-axis.
See an extreme example in the testmodel below: since there is nothing to support the long overhanging arc, the printer prints in the air, and the extruded sausages do sag. As you can see, the problem starts at a certain angle of overhangs. This angle depends on layer-height, material, temperature. If I would not want this sagging, I would have to switch-on support. Then it would print a sort of construction scaffold below the overhang, to support it.
If you are totally new to 3D-printing, I would recommend that you design or find a couple of test models, and print them with various settings. Keep watching closely while it is printing, so you see exactly what happens. In this way, you will get a lot of understanding and a feel of it, in a short time. It is well-spent time.

Hi, Thanks for the reply and help.
I had seen the supports setting, so switched it on, but it has done nothing. (although I have not tried to print yet).
I have an A20T, (currently not functioning, awaiting new mother board). I was thinking of printing with the Extruder 1 (white) and selecting the extruder 2 (Black) for the support.
But currently stuck and am doing the research to learn about Cura.
I was thinking that the supports would show up on the actual model on the screen?
Regards
