Schedule K-1

[MA37]

I just received a Schedule K-1 (for calendar year 2020) from a company (LLC) I previously worked for where I hold some incentive units.  I have never received a K-1 from them previously as I only became vested in 2020. 

The Schedule has no entries in Part III except for Box 16.  Code is "A" and entry under Foreign Transactions is "OC".  There are "Partner Footnotes" included that refer back to various boxes on Part II and Part III, but none of the referenced boxes have anything filled in.  I'm trying to figure out if I need to do anything with this.  I have already filed my return and received a refund.  Do I need to file an amended return?

Thanks for your help!

Then you probably don't need to do anything including filing an amended return. Those entries in that field are usually just to figure a foreign tax credit anyway.
