[ONEferBRID]

As the others have stated, a 2♠ rebid ( showing 5+cards ) by Responder (playing Lebensohl-- 2NT! here as the start of a sign-off) is forcing over a reverse.. It's close, but you just have enough to make that bid.
3♦ is also forcing and natural ( and not 4th suit forcing in the usual sense that it could be artificial -- 2S is enough to show 5 cards ) .... but Responder is not strong or shapely enough for a 3-level new suit rebid at this juncture.

1C - 1S
2H - 2S
3C - 3D
3NT

I was responding to KQR's real auction. In that auction, 2S would no-longer show merely 5, but 6+, since opener denied 3 spades earlier. 2NT (less than 9 HCP) would not get a 3C rebid by opener, because his hand is too good. Thus, Opener can freely show his big hand and HX of spades by bidding 3S. That leads to a makable contract of 4S or 3NT.

You can keep your smug "ask the better players" remark to your self, Gibson.

south is not close to 4♣ over 3♦, he should bid 3♠ or 3♥, he has 6 clubs, but they are awful, 3♠ bid its much better.

right (maybe 3♥ is best. The suit is good enough and less risks for misunderstanding. ...3♠ is also good to avoid 5-6 misunderstanding. Theoretically best I think)

Reading aquahombre I realice you play transfers over 1♣, 3♠ is mandatory then as he points out, south denied 3 spades and he has the best possible suppport now: Hx

Thx to the transfer you should land in 4♠. wich is the best spot.
