I am filing an amended return 1040X for my 2019 Tax return, as I did not report my 2019 cryptocurrency activity in my original return. I modified my return and I also used Cryptotrader.tax to generate my 1099-B forms for my short term and long term capital gains, and my Form 8949. I will have to mail in my 1040X form with the supporting documents. My question is: Can I just mail in a Schedule D, along with the 8949 form without the 1099-B forms? If I mail all my 1099-B statements, I would have to print and mail 40 more pages! I don't feel like sending that much and I suspect the poor workers at the IRS may not care to see that either.
