Hi jaylyne,
You're on the learning path to patience !
Considering the current size of the trees I wouldn't cut anything. They need wood to make leaves to get growing.
From such small bushes - that I myself have bought several times: goutte d'or, madeleine des deux saisons, unknown BT2 - it takes me 3 years to get fruits ...
Goutte d'or 4yo is fruiting and started fruiting last year, Mdds 2yo still no figlets, uBT2 2yo still no figlets even with pinching.
But once they start fruiting, they'll keep up - unlike plums as plums do have years off .
The main advantage with TC or such small plants is that they tend to bush, and in the 3 years that they'll grow, you'll get at least 5 trees out of the first one that you've bought.
Sorry, but patience, good cares and look at the bright sides (several trees out of one ticket at the start)!
