Did you receive an actual HUD-1 Settlement Statement at the closing? If yes, confirm it's the same version as the one at https://www.hud.gov/sites/documents/1.PDF
The "OMB Approval No." is in the top right corner. Does it match? If not, then what approval number do you have?
Basically, for you as the seller, costs associated with selling the property are referred to as sales expenses. They include things such as staging fees, (which may or may not be shown on the closing statement) and of course the realtor's commission you paid from your gain, as indicated on the HUD-1 lines 703-704, as shown in the block under the column for "Paid from seller's funds at closing". Note the line numbers may be different if you don't have HUD-1 Settlement Statement with Approval No. 2502-0265 in the upper right corner of that form.
