So, from what I have learned reading this (link below), if Box 20V is greater than $1,000 you need to file a Form 990-T. In my case the number in box 20V is -1.015. I will try to reach someone at the brokerage to see if they can advise me on anything, but if the number is negative I have to assume tax is not owed. Perhaps Sunoco does not generate UBTI, or at lest did not in 2020?

I definitely don't want to file an amended return over this unnecessarily. I am still confused why TurboTax indicated the K-1 was unnecessary to file without any sort of calculation of the data on the K-1. It dismissed it as soon as I indicated box I2 was checked. This information is hard to find and is not terribly intuitive. Yes, I should probably hire a tax adviser, but TurboTax is supposed to be able to do the math given the data.
