it's possible that a PTP Could be a SSTB. i have not seen anything anywhere in the full k-1 package that says anything about SSTB but there are many PTPs and I've only seen a few of them. I would take the position that if they say nothing about it anywhere in the full K-1 package they're not.
also know that there are taxable income limitations based on your filing status. too high and no QBI deduction
