The reason is that Titewad is too fast for 20 gauge.

The 20 does not have the expansion room a very quick powder needs.

I feel your pain, but Titewad is not a particularly low pressure powder even in the 12.

This is not to say that a 20ga load with Titewad can't be developed in a ballistics lab, just that it hasn't been and that's the only responsible way to approach it.
