I got a notice in May 2021. We have accepted your 1040x for 2018. I have no recall of ever submitting this. If I did its over a year since then.
I wish there was an easy way us taxpayers could see what years are complete, what years are pending aka status, and what years haven’t been filed.
Deep state is operating deeper than ever before.
I received a notice that they accepted my fed and state e filing on 3/5/21. The state has sent the refund, however nothing from the feds.
You can log into your IRS account and look at all the forms you filed. You might want to create an account (verification cation in a pain) and look to see if anyone is filing for refunds from previous years.
