♠AT9 ♥ Q62 ♦ AJT ♣ KQT3
and it goes:
1NT-2♦!-2♥- 2NT;
MUST you show the heart fit? (either 3♥ or 4♥ as your judgement indicates.)
Partner could be a flat 5332 hand or he could be more shapely 5422, 5431 with only invitational values.

We (partner and I) don't have the tools to sort it out in invitational auctions after a NT opening. We do have a toy for 1M openings, where the other hand is 4-3-3-3 and wants to give opener the choice between 4M and 3N, but that is not your question.

3N = 10, 3♥ = 9, 4♥ = 8.

It may well be that partners hand improves, if he knowes about a fit.
If you decide to accept the invite, hiding the support is certainly a valid
option, ... my partner does this, I dont, I usually guess wrong, so I prefer
to be on the safe side in the post mortem.
He showed the 5 card in search of a 8 card fit, I have a 8 card fit, I show the
8 card fit.
With kind regards

FWIW on the topic of 5332 shapes, I play responder rebidding 3 of the other major as game force with 5332, then with a 3334 opener converts to 3NT.

Does this mean:
1N-2D
2H-3N=artificial showing some unbalanced hand? That would seem to be a space-consuming inversion where opener still doesn't know the other suit held by responder.
But, the thread is about invites by responder, so maybe I shouldn't have furthered this side issue.

Other suit? Logically this should be a spade splinter with long hearts, no? It seems ok, albeit somewhat risky and prone to end up having to buy a beer or two.

Off topic, but I use this to play. Rather than show a minor second suit, as responder I transfer to it. If my second suit was the other major, I would smolen or jump diamonds conventionally. OK, I have a spare bid, transfer to the major then rebid 3♦, but there is no meaning put on this yet. (BTW I play 15/16 NT with no invitations, so major transfer then 2NT is GF (slam try) transfer to clubs.)
Edit - the 3NT rebid denies the 5332, as that is shown with the 3 other major. No reason why these cannot be transposed. In fact I could incorporate my spare bid to show whether the doubleton is in spades or a minor.

With no invites, you could use something like
1NT - 2♦; 2♥
==
2♠ = 4+ clubs or 5♥(332)
2NT = 4 diamonds
3♣ = 5+ diamonds
3♦ = 5+ spades
3♥ = strong one-suiter
1NT - 2♥; 2♠
==
2NT = 4+ clubs
3♣ = 4 diamonds
3♦ = 5+ diamonds
3♥ = 5♠(332)
3♠ = strong one-suiter
You can get quite a lot more in here if you want to but that is probably unnecessary with such a limited 1NT opening.

With the hand, probably bid 3H or 3NT, depends on how you value the high spots, although on the other hand, what is the point of using an invitational bid after 1NT opening with a point-range of 3?

It is part of the partnership transfer structure. Credit or blame is transferred back to opener for her decision to accept or decline.
There is a contingent of posters who believe that their sims and knowledge of probabilities are better indicators than partner's opinion if they invite, so they just bid game or not. It saves Opener the bother of looking at her hand.
