I have a full CSV of all coins and transactions with dates and I know all of the profit and loss. The turbotax recommendation is to pay a tax aggregator, but that is silly being that I already have all of it captured and calculated. First thought is to just break them out by coin and upload separately. the other thought would be to somehow summarize the transactions to just p/l over various dates but I am unsure how to do that in TT.
You can substitute the form that you were provided for a 1099-B.
You can enter them in to the sales sections even though your crypto statement doesn't break them out that way.
The four sections are -
With crypto (and 4000 transactions) most of your totals will fit in the first two. The IRS will get the statement so you don't have to worry about them being unable to match this stuff up.
You have to tell the system you have a 1099-B and then upload the forms that you have as attachments so the IRS can see all of your transactions.
