As soon as the IRS gets notice, it should stop the garnishment. And it should undo the garnishments that occurred after you filed. If the IRS does not return post filing funds, your attorney may need to file a contempt motion against it. As long as your taxes are dischargeable, you should have no further problems. And if you could exempt the garnished amounts from the 90 days prior to filing, you should be able to recover those amounts as well.
Your lawyer should give notice directly to the IRS and your employer to accelerate the garnishment's end. They should also move to quash the garnishment. Bear in mind that, if the tax debt is not dischargable, if won't do you much good to stop the garnishment since you will only be buying time before they start again unless you can make other arrangements with them.

The IRS is a HUGE bureaucracy and the left hand does not know what the right hand is doing. Eventually the right department will get the word, and stop the garnishment.

I agree with the other answers. If you hired an attorney to help you file bankruptcy, call your attorney and have them call the IRS. The IRS should not be garnishing you while you are under the "automatic stay" bankruptcy protection. Remember, though, that more recent IRS debt is non-dischargeable through bankruptcy. Once your bankruptcy has finished, unless the back taxes were dischargeable, the IRS may start the garnishment process again. Your attorney can explain how that works. If you didn't hire an attorney, some law offices like mine offer free consulations. But otherwise, go through your existing attorney.
