I purchased a roll of 3/16" tubing from Amazon, add said it was copper but
after forming a nice secondary for a small coil I determined it was not
copper, but copper coated steel. How much adversely will this affect my
coil? Should I just toss it, with a lesson learned?

A secondary? from tubing?
In any case, do you know the thickness of the copper? If it's > a few
skin depths at your operating frequency, you're potentially ok.
The real interesting part is steel - it's got a permeability that's
going to increase the inductance. And potentially be lossy.
