Assuming the sale and purchase were done through the same broker the broker will address the wash sale on the Form 1099-B. The 1099-B should have a code of "W" in Box 1f and a dollar amount in Box 1g. You simply enter the 1099-B as it reads into TurboTax and that should take care of it.
The dollar amount should be: (few shares bought/number of shares sold) x $4K.
