I know this may not necessarily be the right group, but I want to see what someone who has done this before. I filed my taxes with a grouped 1099-B, then 3 weeks later got a K1 PTP form. I only use one broker - Swab, which correctly reported all the UVIX buy/sells, including wash sales, but I did not know I would get a K1. It does not change the taxes I owe, but has anyone done this before? Think I should amend or do not bother with the K1
