I am assuming that you're talking about the Internal Revenue Service (IRS) which is the federal government, and not the Department of Revenue (DOR) which is for the State of Florida. In any event, I would start by calling the IRS and requesting an Account Transcript and written documentation of any levy they received. Odds are that the levy that they show was in excess of the $4,798.00, but you'd have to get the paperwork to find out for sure. If they in fact did not send the right amount, then they should correct it for you without having to go outside the IRS. Their number is 800-829-1040 for individual tax payers. Good luck.
