An alternative is to pay the tax at irs.gov. you can pay the amount owed so that you don't incur additional interest. Then you should add the amount paid in the "Estimates and Other Taxes Paid" section of Deductions and Credits. When you get to the "How much did you pay in federal estimated taxes?" question there is a place at the bottom for "Additional Payments". Enter the new tax payment here. The Federal Refund box at the top of the application should go to $0. Now, all you need to do is wait for Turbo tax to fix the problem.
