First time handling PTP on tax forms after trading UVIX

[ZachV]

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. So I already filed my taxes this year, and I'm trying to decide if I need to amend. It does not change the taxes I owe, but has anyone done this before? As I will neither owe nor receive any additional money, do you think I should amend, or do not bother with the K1? Also, if I do amend, file before or after April 15th? Thank you!

The sale of the PTP was reported on the IRS form 1099-B.  Three weeks later you received the K-1 for the PTP.

If the K-1 does not report any new income or expense information, you do not have to amend your income tax return.

Retain the K-1 and attached information with your tax return information should a tax authority have a question at a later time.
