if you don't have any adjustments (wash sales, AMD, noncovered categories) you can certainly simply input the 1099B as a "sales summary" with proceeds and cost basis. You can enter adjustments/noncovereds as summaries also with adjustments, which will create Form 8949 but without the details and triggers the need to mail 8453 with statement. This mailing is avoided by inputting these sales instead as "one by one" with the details; and the balance of your 1099B can be input separately as "sales summary" without adjustments.
I always input my 1099s and had about 30 adjustments which doesn't take long to enter and the rest as summaries is very simple. Not familiar with futures, I did have some options reported as 1256 contracts which is a different process. Short options that expire with proceeds and zero cost basis may be reported as noncovered securities which creates the need to either use one-by-one or mail the 8453 if you can't import.
