I filed out the 1040 without importing and then printed out all the transactions and mailed them to the IRS. I had some Grayscale Bitcoin transactions that were obnoxious bc I sold a bunch at once but transaction got broken into a number of individual sales to different people so the printout of my3 bitcoin transactions alone were over 200 pages long. Not sure the IRS like getting 700 pages of investment transactions, but they seemed to accept them. Not sure what I am doing next year - but definitely NOT using TurboTax
