Narrative:

In the cruise mode of my IFR flight; I was vectored through the very busy ashville airspace. I attempted to check in twice; but the controller was extraordinarily busy. I was aware that at least one aircraft abandoned their approach due to another aircraft on the runway they'd been cleared to land on; and later heard this aircraft request a return for another approach; which I ended up nose to nose with. Thankfully the perfect VFR conditions allowed me to see this oncoming aircraft. I was surprised that my TCAS (garmin 345) was not showing this aircraft; but it may have been the 2 mile range I had it set on; and I'm not used to seeing large jets that close up. Only a few moments later; I got an audible alert from the garmin 345 of traffic 12 o'clock 1 mile. I don't recall what the vertical separation was. I initiated a climbing left turn as the oncoming aircraft appeared to be turning back to ashville (to their left.) before I could alert the controller that I was climbing and turning; they instructed me to climb to 9;000 ft. (I was cruising at 8;000 ft.). Shortly thereafter; they returned me to 8;000 ft.; and handed me off to atlanta.I don't fault the controller. They were overwhelmed by the traffic - and the go-around; I suspect. But I wanted to be on the record that I deviated from my clearance to avoid a potential collision.
