I am sure that your potatoes will do well.
I managed to get some sweet potatoes to sprout about three years ago by giving them a good scrub and suspending them in some water. I think they spray them with something to prevent them sprouting.
I kept them under plastic all summer, they had every possible TLC. There were huge amounts of lovely leaves, I regretted in the end not eating those. And a lot of very beautiful flowers So I had high hopes of a good harvest but ended up with a few very meagre roots the size of my thumb which had very little flesh inside. I have gone back to buying them.
