The IRS sent me a notice CP81 stating I didn't file my 2021 return. I have a confirmation from TurboTax that it was accepted on March 13, 2022. How do I resolve this?
How do I send form 8862 to the IRS for tax year 2023 if I did my return on Turbo Tax and mailed it in? Can I use the IRS upload tool? Should I include copy of 2023 return
