The ♯11 of E♭ is A
The ♯11 (sharp eleven, written #11) of E♭ (E flat, Eb) is A: an augmented eleventh above the root.
E♭ — the root, 1A — the ♯11
How to find it
An 11th is a 4th an octave up, so it takes the 4th's letter: E, F, G, A.
Then the sound: an augmented eleventh is 18 semitones above E♭, which is exactly where A is — no sharp or flat needed.
