I just parsed your Username here into a first and last name and Googled it. Is that You that is coming up in the search results? If so, see how easy it is to Pretend to be from Intuit?

Pro Advisors do not have access to the Intuit Customer database; Support would not call you like that, either.

So, yes, I would be worried and take whatever precautions would be necessary to lock the doors behind them, now. I cannot tell you about changing credit card or account numbers, etc, because only you know what they saw, had access to, might have Copied or Cloned, etc.
