Last year I sold 100 shares of one of my stocks in ONE order. However, I didn't buy those shares at the same time. They were from multiple purchases at different times (around 7 times). In my 1099B form, Fidelity shows profits for each of the separate purchase, plus the total profit for the whole 100 shares.

So my question is when I file tax, do I report the sale of 100 shares as a single entry, OR do I have to report individual purchases separately, which will be very tedious.

Thanks in advance.
