The LLC that has not sent the K-1 went out of business in 2017 but was still in business in 2016. The K-1 will reflect a loss and no distributions. However, I don't know how much the loss will be.
1. Should I file with the 2015 numbers (also a loss), leave a note, and amend as soon as I have the K-1?
2. Should I not include the Schedule K-1? And amend when I get it?
3. Should I not include the Schedule K-1 and file an 8082 with my return? Then amend when I get it?
4. Should I file a 4797? (It seems like I should do this for 2017 not 2016)
5. Something else?
