Kasia,
The plants create fruiting buds in late spring. It is possible that your plants made the executive decision to invest all resources in 2019 to promote
root growth to establish a firm foundation. I can't say I would blame the plants for that, being transplanted is stressful. In fact
alot of folks will say that when you transplant a tree pick off any blossom or fruits that you see to help the plants better establish itself.
It is also possible the there wasn't
enough fruit promoting minerals in the soil. Or in a similar fashion there was too much leaf(nitrogen) growth promoting mineral in the soil
Pickles,
Apples are usually not self-fertile, so they don't come true to seed.
While the 'mom' was a honeycrips, the pollen donor is most likely a crabapple (different species but same Malus genus). The offspring of both can fruit but usually closer to a crabapple flavor profile. I also find that the seeds that produce shrubby looking plants like the ones you have pictured then to never bear and I call them 'male-sterile plants. But it has only been 5years and seed grown fruit tree take quite awhile to fruit unlike ones from the nursery that comes leaved out and already fruiting.
Iterations are fine, we don't have to be perfect
