I have a (2) K-1s  on a 2021 estate return that needs to go to  foreign beneficiaries.  There is no income, the K-1 just shows deductions that this person would be able to take.  The foreign beneficiaries do not have a US TIN.  I don't  have their ID numbers from their country.      I do have "foreign beneficiary" checked.    I have an error message that would prevent me from filing electronically.  I read a 2020  post that you have to file a paper return in this case.  Is that still the case or is there a work around that would allow me to file electronically in  2021

Thanks!
