I have a couple scenarios I'm a little confused on:
(1) If I calculate my crypto transactions (gains/losses) myself entering them on form 8949, how does getting a 1099-B from an exchange for those same transactions affect things? What if they choose to calculate gains and losses differently (i.e. FIFO vs LIFO vs Average Cost Basis) and there's a difference between what I report and what's on the 1099-B?
(2) Also, when reporting the above transactions myself which box would get checked on Part 1 of form 8949 (A, B or C)?
(A) transactions reported on Form(s) 1099-B showing basis was reported to the IRS
(B) transactions reported on Form(s) 1099-B showing basis wasn’t reported to the IRS
(C) transactions not reported to you on Form 1099-B
