No reply yet?  Nuts, I have exactly the same question.

It's YOUR question, from 2021.

LOL 🤣

Oye! 😂

Er.. I guess I STILL have exactly the same question. 

And no answer. I've searched elsewhere, hoping another software product would have a usable solution. Somebody dying with a lot of suspended losses and a large step-up can't be THAT rare, right?

Any input that gets you the desired output is fine; when it comes to K-1s, the IRS sees none of the input and only the output.

Do a schedule in Excel. Figure out what losses, if any, free up, for each pass-through. Set up new K-1 entries for those entities, assign those allowable losses to the freed-up entity, and mark them 2=delete next year.

A large step-up usually eliminates the problem. It's only an issue when, and to the extent that, the PAL is larger than the step-up.

Sorry, got the PAL and step-up reversed.

No pass-through entities involved. Just a taxpayer-owned rental condo.

Same theory. Adjust the carryover so the total allowable amount is right, and mark it 2 = dispose next year.

Many thanks!
