TurboTax Support doesn't normally phone foreign countries. What about in the other direction? Can you phone 800-type numbers in the US? (won't be free, and some countries don't allow it.) If so, we can tell you how.
If you have X (Twitter) or Facebook, you can use one of those to directly contact a TurboTax Support agent with messaging and ask them to tell you your best option for receiving support:
