You drew the Province with your Tournament. You can only reveal a Province that was in your hand before Tournament drew a card.

Tournament doesn't draw a card: +1 Action. Each player may reveal a Province from his hand. If you do, discard it and gain a Prize (from the Prize pile) or a Duchy, putting it on top of your deck. If no-one else does, +1 Card, +Coin.

Then if i play summon: Gain an Action card costing up to 4 Coin. Set it aside. If you do, then at the start of your next turn, play it.

Set aside tournament, in my new hand cames a province but i my new turn i can't reveal it.

The Province was not in your hand when Summon played Tournament at the begining of your turn.

I bolded what happened. You drew a province in the end of the tournament play, so you couldn't reveal it.
