My mother passed in Feb 2020 and we filed for her as a deceased person but we mistakenly filed her date of death as Feb 2019. Do we need to correct that with the IRS? We had to file a copy of the death certificate and her return was accepted. We did finally get her refund, but it took a long time. We need to file 2020 taxes for her. Is it ok that we report the correct date of death?
