My dad has dementia and just told me he is unable to do his own taxes. I can't help him today because I am at work. What should I do?

Sorry to hear of your father's situation. If you would like, you can use the TurboTax software to file a free extension for your father today and that will buy you time until mid-October to help him with his taxes.
