Regina learning magic doesn't necessary mean it happened 20 years before the curse... I think that in 4x14 Snow was let's say in early 20s (we saw her figure on a horse), so it's safe to assume Aurora was cursed for 8 years maximum (if we stick to the fact that Snow is, literally, the same age of Emma, aka 28). She said that she felt that only one year passed but it was just her sensation I think.
