IRS requires all sell details to be supplied on Form 8949,
or on your own forms (e.g. consolidated 1099-B or spreadsheet) 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.
This includes crypto transactions, which you are reporting.
This year there is also a box to check that you have crypto transactions.

As an active investor, be aware that your category Box A sales without adjustments do not require Form 8949, so there is no reason to import those transactions.
Instead use the "enter a summary" option to put your numbers on Schedule D Line 1a or Line 8a.
The actual date is not important, thus various is a perfectly acceptable entry.

if your 1099-B doesn't show category A or D, then you can make the mail-in election.
