Very much appreciated @RobertB4444.
I did exactly as you suggested-- created a second file with the "amendments" including correction of my address; just finishing it now.
So should I actually FILE IT?
The only issue really is whether it hurts ME prospectively to have an old address on this K-1 two years running. I converted my former home in California to business use mid-2021 and planning a 1031 Exchange later this year or early next year. At time of sale, I should have 24 months primary residence (part of 2019, 2020, part of 2021) and 24 months business use (part of 2021, 2022, part of 2023). Therefore qualifying for both a primary residence exclusion of 250k gain, and the like-kind exchange exclusion/deferral of the balance of "capital gain." Tight squeeze into the preceding five years but it's there. That said, my move was messy, has taken a long time to execute; I don't want a trail of "evidence" that suggests I didn't really move, like filing a K-1 showing my residence address/state as the now business address in CA, when my primary residence is in TN. I was lazy (i.e., extremely busy) and just forwarded mail for a year, didn't get the new drivers' license right away etc ... This will be the subject of another post I'm sure on 1031 exchange execution. As "date moved" or "date residency established" seems a lot more fluid when you do it in real life, than IRS forms would make it seem!!
THE QUESTION: If it doesn't cost (but an e-file fee?) to file 1065X, and I've already gone through all the steps, then is there any harm to send it in to the IRS? Or am I overthinking?
