Charlesmhorton: You should still receive your refund as expected from your original return. After that, you can prepare your 1040-X, the form for the amended return. Once you've prepared your amended return, you'll see if you owe additional tax or receive additional refund. (This will depend on the income/withholdings, etc. on your additional tax document).
If you'd like to contact TurboTax Customer Support by phone, navigate the link below. You'll have to enter a little info first (necessary to connect you to the right assistant), then proceed until you see the option to "Call". During business hours (currently 5AM to 9PM, Pacific time, daily), you'll see a telephone number displayed.
