Do I need to attach this Summary from Gain/Loss report for cryptocurrency not reported on Form 1099-B?
I have a taxpayer with cryptocurrency sells and converts that are taxable events that realized gains or losses. None of these transactions were reported on Form 1099-B. Do I need to attach this Summary from the taxpayer's Gain/Loss report to his 1040 Tax return or do I need to attach all 12 pages of the report in which the other pages show the detail for converts and sells that include Date Sold, Event, Amount, Proceeds, Cost Basis, Long Term Gain/Loss, Short Term Gain/Loss, Total Gains/Losses, as well as Date Acquired (Tax Lots)?
