I've had my identity stolen or possibly stolen so damned many times I just don't GAF anymore.
If Intuit is hacked, "Big Sky Theory" applies (for those unfamiliar, the concept that, pretty much, you can point airplanes any which way, randomly, and not many will hit each other, because there is a lot of sky out there).
"Big Dump Theory" or something is the closest I have. Basically, using one stolen identity? Easy, fun profitable. Using 10? Eh, doable, but annoying. Using 10 million, 50 million, 100 million? Forget it. You cannot scale identity theft that way. Same thing for credit card theft. I'm sure my CC #s are in dozens of darknet dumps, but people just haven't gotten around to using them.
There's a very good chance that if Intuit gets their cyber-asses handed to them, I'll find out about it in time to do something useful like change my passwords.
If not? Well, that's a risk I'm willing to take. No different, really, from my home computers getting compromised with some stealthy malware and stealing my passwords. *shrug*
It's just really, really far down the list of things I worry about.
