First you need to see if they are really gone. I've never seen anyone make that claim, but there are a way lot of forum questions that I haven't seen. I can't see how TurboTax would have any kind of write privileges in your financial accounts.
Discover has 24x7 support, so you could reach them this weekend. Fidelity you may not be able to reach until Monday.
TurboTax Support is open later today, but they're going to ask you to first check with Fidelity and Discover since they can't check on your accounts there.
Watch for additional comments in this thread during the day today.
