Did they send you a check for the $17K? If so, what date did you receive it?
If they sent you the money and you do not redeposit it within 60 days of receipt into a new HSA, then you will owe ordinary income tax plus a 20% penalty on any amounts that exceed your qualified medical expenses. I personally would avoid this ordinary income tax and 20% penalty situation as much as humanly possible.
I personally would prefer not making the withdrawal for the accumulated qualified medical expenses. I would prefer to save those receipts and let the money grow tax-free in the HSA for longer, especially if I were young. The only exception would be if I really needed the money to make rent or pay basic expenses (doesn't sound like you, but maybe).
It really doesn't make sense to me to redirect the money from the HSA into the Roth IRA, unless you've changed your mind and are certain that you won't have enough qualified medical expenses to drain the HSA at some point in the future.
Fidelity seems to have a pretty great HSA account, so if you decide to recontribute the money I'd give them a look.
