The IRS does allow you to make summary entries on your tax return, but then you have to mail to the IRS a statement listing each individual sale. You have to send the details of each sale to the IRS one way or another. And you have to make separate summary entries for short-term and long-term sales.
When you start to enter a sale manually, it will give you two choices: "I'll enter one sale at a time" or "I'll enter a summary for each sales category." Select the second option, and it will then give you boxes to enter the total proceeds and total cost, and select the sale category: short-term or long-term, covered or noncovered. (All crypto sales are noncovered, at least until 2023.) After that screen, you will get a screen that asks if you need to enter another sale, meaning totals for another category. You have to enter separate totals for each category.
The statement that you send to the IRS has to contain the same information as Form 8949, in a similar format. The information needed is a description of the property sold, dates of acquisition and disposition, proceeds, basis, adjustment and code(s) if applicable, and gain or loss. Put your name and Social Security number at the top of each page of the statement.
If you e-file your tax return, TurboTax will create a Form 8453 for you to print. Attach the statement to Form 8453 and mail it to the IRS promptly after your e-file has been accepted. If you file your tax return by mail, attach the statement to the return, behind all the IRS forms and schedules.
