What e-file acceptance information is available?
I received my TurboTax Business e-file acceptance on 31-Mar-2026. I received a notice from the IRS dated 20-April-2026 that my return was delinquent and am assessed a penalty. Since I am confident that this information comes through some type of EDI feed, I am sure it is date and time stamped and that there is a reference number. How can I find this information?
