Let's say I have 20 different sales of Ethereum, all on different dates. I have good records of the dates acquired, dates sold, cost basis, and proceeds for each. Let's say they are all the same category (i.e. all short-term). Ordinarily these would be reported on 8949 with box C ("short-term transactions not reported to you on form 1099-B).
Given that they are all the same asset and the same category (box), rather than having to list each of the 20 disposals separately, can I just sum them to a single entry, with the total cost & total proceeds, and list "Various" for "Date Acquired" and "Date Sold"? Given that the net result is the same?
Or to put it more broadly, as long as you only sum "within assets" (i.e. you only combine sales of token x with other sales of token x), and as long as you only sum "within categories" (i.e. you only sum among items that have a given box checked), is it acceptable to consolidate like this, to avoid having to enter potentially hundreds of small transactions one at a time?
