The program I wrote to create the txf files for my trades can easily be tweaked to calculate FIFO and wash sales based on the coin/stock instead of the current coin-per-exchange/wallet. I'll need to do that starting next year I think with updates written into the stimulus bill. However, the issue is that the txf file DOES encode which box to check but TurboTax completely ignores that and you have to update it for each trade at the expense of 4-5 clicks and several seconds each (times thousands for many people).
