Such a computation would require an infinite input tape (to specify
the irrational), which isn't considered a computation.

A computation in the sense of the ultimate result of a Turing machine
-- the final tape produced after the machine halts (or the limit of
the tape at infinity, which would allow for transcendental numbers to
result from non-halting computations). As I mentioned, this result is
accepted as proven by the mathematical community -- there are only
finitely many numbers that can result from computation, even using an
infinite number of steps.

Your other claim seems to me to be correct.
