>>1316950indeterminate growth plant do this thing, growing a new stem between the main trunk and a side leaf branch, that will create an entire new plant if left there, but since the tomato keeps throwing them out it will lead to an unbalanced plant, you have to remove those while they are small, so the plant has mainly vertical growth
you can leave one at the basis, so you will basically grow 2 plants from one, but that's it
you can also cut them to grow more plants but thats probably beyond your interest now
just remove as many as possible, even if it's late it wont be a particular problem
