K-1 and unit sales of MLPs in my Roth IRA

Hi

Yep I sold 198 units of SPH (Suburban propane) 0n 3/24/2022. Bought 326 units on 1/11/2022. 

This was in my  Roth account. I am over 60 years old. Roth is 20 years old.

Received 2022 Schedule K-1 last March (2022). 

Box 20V shows    -306

*STMT shows.....   20V1 -306,  20Z1 -306, 20AB  202,  20AE 197,  20AH1 1,790,  20AH2  0

If I'm correct my broker had no need to file a 990-t  for 2022 (less than $1000.00 income).

I am assuming sale of units with gains and dividends less than $1000.00 would not create a taxable event.

I'm not sure 20AH1 Gross Profit (Income)   $1790 is part of my gains or Dividend income.

I'm sure if i should have attach IRC Section 751 Statement to my 2022 tax return.

Any help be appreciated.
