Taxpayer died in 2021 before filing 2020 tax return; completing return now (on extension). There is a court-appointed executor (son-in-law of deceased) to settle the estate and sign the return.
Does the letter from the court need to be attached to the 2020 tax return? There will be both Federal and State refunds. Is Form 1310 required to have refund sent to executor? If so, will these two requirements prevent electronic filing? The IRS Pub was not crystal clear on these requirements.
