IRS say ignore CP80 for 2020 (2023 Update)

It is possible that the IRS has suspended the issuance of CP80 and CP080 notices due to processing delays caused by the large volume of 2019 and 2020 tax returns they have received. This means that if you received a notice for your 2019 return, you should refile it, but if you received a notice for your 2020 return, you should not refile it.

It is possible that the CP80 letters were auto-generated by the system when processing of 2021 returns began, and now the IRS is overwhelmed with more returns that it cannot process. It is important to follow the instructions provided by the IRS, and not refile your 2020 return if you received a CP80 notice, unless you have been advised to do so.

It's important to note that the IRS's instruction may change and it's always best to check their website or contact them directly for updated information. Additionally, it's recommended that you consult with a professional tax advisor to help you navigate the rules and regulations, and to understand the tax implications of your situation
