I don't know about a "filing queue," but the invalid signature date problem will NOT let you e-file an amended return and short circuits the process. I just attempted to e-file but the first error message said my electronic signature of today's date was invalid because it wasn't between 1/1/2025 and 12/31/2025, so I accommodated by entering the original filing date of 2/4/2025. That brought up another error message that said I couldn't e-file because I was past the e-filing period which ended 11/15/25. It seems to be a glitch with the Turbotax software but when I call, they say wait until the IRS accepts e-file on January 26 and all will be well. I doubt it but we'll see. BTW, there is nothing wrong with my forms for filing (or e-filing) that I can see, and TT doesn't find any errors.
