Amending 2021 federal and state return doesn't work
I need to amend both my federal and New York state returns but TurboTax Online tells me these two things when I try to e-file the amended returns:
1. For the federal return it wants me to file by mail because "E-file is not available because your original return was not e-filed." – This is NOT true, I did e-file the federal return.
2. Getting this error when trying to e-file the amended New York return: "Your transmission didn't go through. Duplicate Social Security Number: A tax return with the same Social Security number has already been submitted ..."
I already received both the federal and state refunds but now I have both federal and state tax due. Yet TurboTax doesn't reset the state refund counter to zero but instead it shows a lower refund value than what I actually received. I would think that it would show the tax I'm due now (the difference between the refund I already received and the refund it shows now after preparing the amended return). But that's not the case.
(The change I need to make is adding a new 1099-INT.)
Are these bugs? How can I now e-file my amended returns if TurboTax doesn't let me when I believe it should?
