IRS Letter 916C dated September 10 saying it's incomplete.
If anyone can give me insight as I'm confused atp. I filled my return in April didn't know I had to sign it before I mailed it as it is my 1st time doing an amended return. So I finally seen movement in July which was basically a letter stating I didn't sign it they mailed it 7/15/26 I received it 7/30 and I mailed it back signed the next day 7/30 certified mail and they received it the following Tuesday. Now this is where it gets confusing...
I had no movement on my transcript nor wmar until 9/4 my transcript updated to 290 $0. Then 9/11 wmar says they adjusted my return and I should get a letter in 3 weeks. BUT then I received a letter 9/12 dated as 9/10 stating "we can't process your claim for the tax list above. On July 5, 2025 (yes it says 2025 even though we are in 2026, it was amended this year for this tax year) we asked you to send a signed copy of your tax return for the tax year December 31, 2025, because you did not sign your return. We can't process your return because we didn't receive the information we requested please sign and get a copy of your amended return." I am so confused by this. Did the system just lag and did not know I mailed in my signed amended return because they are behind or what? Any advice on how I should move forward would be greatly appreciated!
