They haven't provided a form yet were advised of the estimated amount and just received the net proceeds. I expect to see 1099 later. I listed the tax w/h on Additional Tax Pmt 1 under the ESTIMATED TAX PAID AND PRIOR YR OVERPMT. the Gross Proceeds I currently have under 'Taxpayer other income not subject to SE tax'

Curious if there are better sections to list these. Thanks!
