If you don't have a different card you can try, you'll need to call customer support. First, however, call your credit card bank to see if they have put a hold on your account or if there is some reason they are denying the charge.
@connorjanet - also, if you call the bank, ask them if they see the transactions being denied. if they do, it's a problem with your bank / your card.
if they don't see any transactions being denied, it's a problem with Turbo Tax as the transactions never reached the Bank,
