STOP sending copies ... amended returns are taking 6 months or more to process this year and sending in multiple copies can cause further delays. Once your envelope is finally opened and the return it entered into the system you can get a progress report here : https://www.irs.gov/filing/wheres-my-amended-return
First of all, thank you so much for the quick reply, @Critter-3 .
I will stop sending copies (I only sent a second copy), but the first copy was sent back in January. Could it be an 11 month delay in opening the letter I sent? That seems excessive to say the least. I understand that the IRS is being swamped with COVID stimulus problems, but again, 11 months seems to be quite a bit of time...
Again, thank you for the quick response, I am grateful.
Amended returns are normally not addressed until March or later even for prior year returns and due to the covid shut down this year millions of envelopes piled up for months and the IRS is slowly playing catch up with a reduced staff so patience will be needed.
