Does Turbo Tax allow efiling of amended return beyond the calendar year of the original return? Why will it not accept current date for signature?

For example, I need to file amended returns for 2021, 2022, 2023, all of which were originally efiled with TT. I have the amended returns prepared within each proper TT program, ready to efile, but once I add today's date on the signature page it is picked up as an error and I am told the date must fall within the calendar year of the original return.
