Why the turbotax generated form 8949 doesn't include transaction details for coinbase crypto transactions?

[llc_com]

After I auto-import my details from coinbase (by connecting to my coinbase account, not by uploading a csv file directly), I can see the list of transactions available. So I worked all the way until I can choose how to file in the end. What's weird to me is, since I decide to file by mail, after I printed out all the forms, what I can see for my form 8949 is that it has only one transaction called "Coinbase - see attached statement"  with the aggregated transaction values (proceeds, cost basis etc.). But the whole printed state+fed return doc don't include any attachment at all to explain what that entry is. Is this expected? How can I resolve this?

Your Form 8949 is showing a 'Summary Entry' of your Coinbase transactions, which is typical of crypto transaction reporting, even though the imported info was used in calculations.

If you are mailing your return, attach a copy of your transactions to Form 8949.  This can be any format you choose, such as a .csv, spreadsheet or PDF file, just to show transaction details.

Here's more info on Reporting Crypto Transactions on Form 8949. 

Per Champ @fanfare:

"IRS requires details to be listed on Form 8949, or on your own forms (e.g. consolidated 1099-B) which have the same information and in the same manner as Form 8949.
Either way, if you choose to summarize, you have to mail the transaction details to the IRS within three business days of IRS accepting your tax return.
Exception: if you summarize Category A or Category D, Form 8949 is not needed for transactions without adjustments. No mailing is necessary. TurboTax won't ask you about wash sales if you don't check the box.

Your 1099-B will tell you what category your transactions fall into.

no 1099-B? that's category C or F."

you're saying :

you itemize your crypto details.

TurboTax summarizes it.

TurboTax forces you to mail in your details because the details are not on your e-Filed return.

This is pretty poor service.

PS when mailing details they have to be on Form 8949 or shown in the manner of Form 8949.

a crypto CSV file does not meet that criteria.

I have the same concern as @fanfare . If I am going to attach details, then I don't have a detailed transaction list that matches the format of 8949, which I believe is a requirement for 8949. Also on TurboTax I added cost basis to a couple of transactions so only TurboTax has the ground truth for what it puts on the generated 8949.

Wondering if it's possible that turbotax writes out the details directly rather than providing an aggregated transaction in this case. (Or let TurboTax generate a detailed list)

there have been questions on the forum for years about how to report crypto but couldn't get import of csv to work.

I use to think you could just reorder your csv file into the order on Form 8949.

then somebody posted a sample CSV file.

It would require major programming to turn that into the form and manner of Form 8949.

This is the first thread I've ever seen that says, after importing CSV file, it is collapsed down to one summary line.

maybe that is new behavior this year. (I  don't have any crypto transactions)

maybe its always been doing that. First I've heard of it on this forum.
