Thank you for your response.
We're doing the 2020 trust taxes now. We can put the disbursements in 2020, but what do we do with the 2019 K-1s already filed? Do we amend the 2019 trust tax return without issuing K-1s? Asking all the beneficiaries to amend their 2019 tax returns for income they didn't get in 2019 doesn't seem right.
Should we call the IRS to see what they want us to do?
